I don't agree, but why isn't important. Neither is your reasoning for not wanting them.A lot of discussion has gone around regarding the playtest fighter. I've heard a lot of people say that because the fighter is too simple and boring, 4e style "powers" should be available to the fighter (and perhaps to all classes). I respectably disagree. Encounter powers are something that should be kept out of D&D next.
5e's mandate is to be oh-so-'inclusive.' I've heard excellent arguments why Vancian casting is a game-wrecking abomination and should never see the light of day again. They don't matter, because some of those folks WotC wants to 'include' love Vancian casting. So Vancian is in.
If someone objects to Vancian classes being un-balanceable or Psionics being genre-inappropriate, or whatever, the response is "well don't use 'em in your game."
If you don't like encounter powers, don't use 'em in your game. If you don't like martial classes being any good, don't use 'em in your game. Ban them: tell prospective players, "This is Harry Potter D&D, no muggles allowed!"
