When you want to play an actual superhero, and are constantly told, no, play "Mortals, the Dysenterying," instead, one starts to feel a lot of sympathy for that position.
Now, of course, people wanting to play low magic gritty fantasy is perfectly okay if that's what's fun for them. But...
After so much stormwind and "noncasters should remain mooks" and "actually using your class abilities intelligently rather than pandering to some grog's nostaligia glasses vision of AD&D means you're an munchkin" ....
Well, you start to hate people who say that D&D should be low fantasy.
I don't agree with Mistborn's logic, but boy do I sympathize a lot with the emotion behind his/her argument.
See, the problem here is that the Grogs don't actually want a low magic game. They want a high magic game except nobody but wizards get magic. Which, in fact, isn't actually an inherently
bad design. I mean, that's basically what Exalted is, the Exalts are magical superpowered fight wizards and non-fight-wizards are mooks. The thing is, they insist that they should do this and that you should have non-casters as
actual PC options and claim this is a good idea instead of just a trap.
It's more that the grogs don't understand Negative Play Experiences (and thus defend save or sucks/save or dies) and further want to insist on keeping the NPEs for sake of tradition. NPE, for those of you who aren't familiar with the term, are basically things that might technically be balanced but are incredibly unfun, often because they take control away from the player or have trap options that look cool and end up screwing people over. They're stuff that can be worked around but as a newbie will make you very sad and possibly put you off the game forever.
Infinity, a wargame which I love bringing up because it's fucking awesome (
seriously), did a bunch of things to remove negative play experiences recently. They reduced the power of Rambo options and removed a lot of indirect fire weapons from the field because they were plenty balanced in normal play-but against a new player, an Avatar or Jotun showing up would probably wreck
the shit out of you and you would not have much fun because you wouldn't know how to build and position your army to counter Rambos.
Magic: the Gathering has recently removed most if not all land destruction cards from the current format, because land destruction is balanced-but it
is ridiculously unfun. "Oh hey I get to sit around doing nothing because I have no lands." etc etc. Same with the evolution of Magic counterspells, if you look at them. You go from the UU catch-all generic Counterspell to a bunch of more expensive and/or less powerful counter effects.
Or Exalted. Shaping defenses exist to remove NPEs, but the biggest NPE in Exalted is Paranoia Combat.
