I'd remove all references to "Unless the DM changes this" and tell players that it's up to them. After all, do you tell your fighter players what feats they can take? Do you dictate what weapons they can and cannot use? How about any other class? Why do casters get to be special here? Players of every other class get to customize their character to a pretty large degree. To the point, where, in 3e anyway, two fighters could possibly not share a single feat. The only points of similarity between the two characters would be the rate at which they gained feats.
And, depending on other factors, that might not even be the same.
So, why is my game now being dictated by WOTC - after all they are the ones who are telling me that classes will look a certain way unless I, the DM, change it. And, why is the DM getting to dictate to the players?
Isn't it a lot better to let players play the characters that they want to play?
Sorry, it's not 1982 anymore. Viking Hat, My Way or the Highway DMing isn't really the way to go anymore. Is it?
Why stop there? Why put physical descriptions of elves in the PHB and let PCs decide if they're Legolas or Dobby the House Elf? Or give personality archetypes for dwarves, since the PC can play him however he want anyway. Hell, why not let any class use any weapon and armor they want? I want my monk to do kung-fu in full-plate, why should the rules limit me? Speaking of which, the rules for AK-47s and lightsabers better be in the PHB, since I don't want my fighter limited to what weapon he can take. Oh, the PHB BETTER have warforged; there should be plenty of room for them since we're cutting out the physical and personality elements out of the race descriptions.
Player entitlement should only go so far, otherwise you end up with no consistency.
