As I've always said, the real question is whether the Psion would be harmful (explicitly) to the game, not whether or not it's more or less popular than some other classes.What does "necessary" even mean in this context? It's a game; NONE of it is "necessary." If the wizard was missing and we only had the sorcerer and warlock, would the wizard be "necessary?" Or would people just say "fluff your abilities like you're using a spellbook?"
Necessity is a weird argument in a make-believe game; how about what's fun? There's clearly people that will have fun with a psion. More than other classes, even (I saw way more psions over 30 years than I did druids, for example).
It's bizarre to oppose other peoples' wishes for fun within the game, it really is.
