To anyone having problem with the party system I say keep it but since most stories are crossovers make sure that every non gamer has a class. The gamer itself is a class that can learn/do anything, NO ONE ELSE CAN! This means if you invite someone to your party that has an ability their class will focus on that ability and the stuff they can learn quickly using the gamer function will only effect their class/ability. If you invite a normal person they would only be able to learn normal non magic stuff like kung fu or diswashing, but the party system would let them max it out quickly etc...
Class examples would be:
Student - for every day person with no special ability or innate magic (note it is up to the author whether regular people have innate magic or not since 'anyone' could have it even if the original story did not let that character develop it. This allows for unusual ships by allowing side characters the ability to become main characters and then get shipped)
Ninja - Naruto style chakra, allows them to learn anything chakra related with locks in palce for learning elements that they don't have naturally or yet (note with enough time/training anyone can learn any element like Kakashi or Hiruzen). Bloodlines would have their own entirely seperate skill trees that have nothing to do with being a ninja and thus may or may not be leveled up by the gamer system (not all bloodlines can get better but things like the sharingan can where the byakugan cannot... unless author plans to give user tensaigan or whatever).
Witch - similar to natural ability magic user in the original, just someone that can use magic and thus learn most of the gamer magic stuff. Witch is a general term for female magic user so males could have any name from mage, wizard to even warlock or sorcerer as it simply depends on the world/setting.
Mutant - This would work like the Ninja system except their 'bloodline' would be their skill tree. Jean Grey would have two separate trees, one for tekekinesis and another for telepathy and if it is the Phoenix version then another for for that including things like pyrokinesis, fire absorption, healing etc... Or if the author is feeling crazy, they could give Jean Grey the subclass Psionicist and simply allow her to learn everything from one of those huge dnd manuals since literally that is what she is but since no one in the MCU seems to know anything about them, she was never taught any of the esoteric things she most likely would be able to do.
Metahuman - This would include anyone in the DCU (or MCU non mutant) with super powers of any type with subclasses to separate them. Like Kryptonian or Green (other color) Lantern even tho most lanterns don't have any special abilities, but those that do would have more than one subclass as the gamer ability would allow them to expand any of their classes, not just their main one since the ability is broken. This list includes people like Hawkeye and Batman for reasons that should be obvious but to explain it futher... Hawkeye NEVER misses, that's a super power even if many of the universes say he is normal and others say he isn't. Batman is baseline 3 times stronger/faster than an olympian... that isn't normal, not to mention his intellect and ability to build things like ironman or lex luthor.
Basically my point here is, so long as you limit what other people can learn (beyond normal stuff like kung fu and dishwashing) then the party system should be a go. Seeing everyone throwing around spinning mana arrows is just so damn annoying that I never wanna see it from anyone who isn't a witch or the gamer. Hell even Mutants that 'use' magic like Scarlet Witch are not natural magic users that should never throw spinning mana arrows! Her abilities allow her to reshape reality and yes, spinning mana arrows are part of that, but no way should she ever bother to learn it! Seeing her throwing those in a story would be painful to read! Basically giving super strong people access to the party system makes for a boring story unless they can only improve upon their own abilites. Imagine Superman gaining magic immunity... He has no magic and thus should not be able to gain anything beyond physical immunity! yes there are ways to give him access to magic and thus allow him to learn this ability but does anyone even wanna read about Superman fanfics anyways? He is so strong that the only stories with him in it that are popular are romance fics or shameless Si's!
I do like some ideas here, like giving Kiba from Naruto the ability instead of Naruto or anyone with cheatigan eyes. How many fics do I need to read where the Si ends up with Rinnegan before I slit my wrists? Gamers can get much stronger than cheating eyes! Imagine Kiba turning into a 300 foot tall wolf hybrid and having him defeat the Juubi with pure physical strength? Now that would be a good story!
Also Si's with the gamer ability MUST have knowledge of the setting or they are just stupid OC's and make bad stories! Better to give a normal character in the setting the gamer ability than make an OC that doesn't know what they are doing. This however, does not mean they need to have read the manhwa and thus know anything about their ability... Those there is a 90% chance they have at least heard of it, they would not immediately know all the shortcuts and munchkin the crap out of it.
A good example would be one of those lantern Si's that are thrown into the YJ universe except instead of a ring, they end up being blessed by Gaia (since she exists on Earth-16 it would be very easy to explain her giving Jee-hans ability as is without any modifications or long story plots). Then make sure to de-age them to about 15-17 so they get stuck at Mount Harbour and fun time ensues! Especially if they have some funny way of getting noticed (ie falling from space and surviving). because they are level 1 and weak so even though it will be easy to convince Batman that they should be on a team, it will take them a long time to be useful and since some of the hardest missions on the show are at the start... you can see where the story would be hilarious!
Also gamer crossovers should be done to things that the majority have access to. Ie tv/movies vs comics/manga. I don't know many people who actually read comics/mangas unless it is to something they enjoyed in a cartoon/anime/movie first! Most people I know who read a lot, read things without pictures and thus have no clue what people are talking about when reference the manga/comic version of a fandom vs the cartoon/anime/movie version. Gamer fics are already crazy since most of the system is from a manhwa that most readers can't stomach to finish since there are too many pictures and not enough words. Fortunately, these same readers have seen royal road and tons of other litrpg and thus don't need to be handheld or else the audience would be much smaller than it is.
Just some of my two-cents. I'd love to personally write a fanfic but I just have too much originality to follow a script. Prob the best I could stomach is original Naruto ending at the valley of the end as I do not recognized anything that happened in shippuden as something that could be considered canon with what we know of chakra from the original series. I mean, people fighting for days straight vs 15min? Chakra exhaustion happened instantly in the original series yet did not exist in shippuden... A single zombie would destroy a village if the village did not have a seal master (which in the original is all of them except konoha) yet orochimaru wastes it on the Sandaime which does have a surefire way to end it... Basically poor writing imo, just stuff mean to make money and not to make sense! /endrant
TL; DR I tried chewing on your two cents and I choked on them about when you started a comprehensive rant on different "hypothetical" classes.
I agree with the basic message that The Gamer should be a separate class and that party members would have their own specializations, but I have no idea if you said anything else because my eyes glazed over in the middle of the Witch paragraph.
