I laid out my reasoning pretty clearly when I proposed Shii-Cho. It doesn't have anything to do with quester brain; I just think a mastery of the fundamentals will make Anakin a more well-rounded swordsman and Jedi than immediately leaning in to what comes easiest. I expect people prefer that sort of logic over being scolded and belittled.
Well, if you don't think my post describes accurately your position, then I'm confused why you're replying as if I was referring to you specifically? It's not like I quoted you or anything.
The argument that Form I would act as a supercharger for another later Form we pick was definitely being made in the thread, and I think it's incorrect, for the reasons I've outlined. If that's not your argument, then we have do disagreement; as I said in the post you're quoting, there's certainly a reasonable case to be made for Form I.
I'm not sure we want Anakin learning to necessarily take that path to which he seems most naturally inclined. Our choices for the last couple scenes have emphasized conscious self-control over our natural inclinations to lash out at Grievous and Ferus, and Obi-Wan is instructing us to be open to possibilities other than seizing what seemed like a golden opportunity of Palpatine's promise to strong-arm the Senate. I also don't want to "compensate" for neglected fundamentals by leaning into Anakin's obvious strengths. That way lies hiding exploitable weaknesses from ourselves, possibly until it is too late to correct them.
EDIT: that said, Anakin has and will continue to have a lot on his plate (especially since we didn't take Palpatine's shortcut out of having to deal with the Kaleesh crisis), and there is good reason to favor Form V in particular purely for time-management reasons. It is also, IIRC, the first "blue" option in the quest, and while we don't have much Stress accumulated at the moment, I imagine that taking it here would let us devote future actions specifically to burning off Stress by practicing in Form V.
I've championed taking strategically-placed Red options to avoid taking the path of least resistance in the past, but I think that's different from thinking we need to doubt every natural inclination. The lightsaber Form we pick will be important to Anakin, but I simply don't see it defining his character in the same way as important moral choices, who he is friends with, etc.. We can afford to pick Form V if we think it fits him better, just as we can afford to pick any of the other Forms if we have a strong reason for them.
The one exception here where our lightsaber form could have really significant effects on drawing Anakin to the Dark Side might be Juyo, which possibly could go
badly wrong if it goes wrong. I think there is also a chance it really helps Anakin if it goes right; it's the high risk/high reward option.
The QM has already stated that it's not uncommon for Padawans to start of in one style and then switch to another as Knights, once they gained more experience and knowledge of themselves.
Obi-Wan and Anakin both trained in Ataru as young Padawan in Canon before switching to their more well-known styles. And it's also stated that yes, later on one can combine elements/lessons learned from one form to another.
In other words, just because it's the first Form we learn does not mean it's going to be the form Anakin will use to fight in the Clone Wars.
I'm not arguing that Form I is super special powerful. But it's not weak either, Kit Fisto is a fan-favorite fishman for a reason. But it's a good way to shore up Anakin's fundamentals as a young Padawan.
It's unclear when exactly we'll get the chance to pick a second Form, but if we look at when Obi-Wan swapped from Ataru to Soresu, it was after the fight with Maul. Evolving fighting styles is definitely common to all Jedi, but it's normally the result of some important experience or a changed outlook. Extrapolating, I think it's a reasonable supposition to expect that we might get a chance to branch out into another Form (or go deeper into our current one) after our fight with Dooku. That would put Anakin at roughly the same age as Obi-Wan when he started practicing Soresu, and at roughly the same juncture in his career as a Jedi. It's probably worth checking with
@Kirook honestly.
Form I does shore up our fundamentals, but Form V also explicitly is so natural and easy for Anakin that we can essentially double up on training actions for the same action cost. It seems reasonable to me that essentially doubling our training will either provide a similar benefit to ironing out our fundamentals or achieve effectively the same thing. Plus there's the stress reduction. Regarding that: Lightsaber training seems to be a meditative practice for basically all Jedi, so I'm not sure I buy the idea that Form V being a stress reducer for Anakin poses a risk? I think it's just because he jives with it the most.
All that being said, I want to reiterate that I think Form I, or any of the other Forms for that matter is a reasonable option. This isn't life or death, and I think perhaps too much weight is being put on these sorts of cost-benefit analyses.
Probably the most important aspect of this vote is simply about shaping how we want our Anakin's fighting style to look.
