lmao have you read the Ness guide? XD It makes ours look like a three year old made it.
Ness has a very strong community. So does Pokemon Trainer, but they are more disjointed because they are essentially three characters and it's hard for them to make a unified decision as such.
On the other hand, the good chunk of the Yoshi community is pretty immature about their character's shortcomings, stifling their growth. And the Ganondorf community has sort of just settled into their character's tube of mediocrity and just decided to enjoy the ride (which is actually a relatively mature decision).
I'm hoping
this will eventually be something similar to the ones in the Ness forum, but as for ATs...R.O.B. doesn't really use anything other than glide-tossing, wavebouncing, and gyro canceling, which are very quick to learn and incorporate into your game anyway. R.O.B.'s overall game is choosing the strategy for a given situation, anyway, kinda like Samus in Melee, although Samus was relatively tech-heavy, if I remember correctly...
