My my my, we just loooove to hear ourselves don't we?
Not seeing how having choices re: class features really changes the basics of how the game is played. You have resources, you try to figure out how best to use those resources. You may as well criticize a module because it uses different magic items from the DMG.
^^^This, man! At a game-centric rather than character-centric table, all the extra character fluff does is give the players some fun creative stuff to do between sessions, or during downtime/towntime. If you're playing an older style game, that stuff shouldn't get in the way of actual at-the-table play.
