Wizards who can heal themselves with daily allotments of healing? Yeah, a lot of changes I am not in favour of.
As for Pathfinder, it certainly made itself sexy with some persuasive rule changes to draw in players. I've tried the beta pretty hard in my games, but core went too far and I've almost rolled it back to 3.5 (but with some inclusions from beta) due to certain changes trying to remove the weaknesses of classes (like taking wizards to d6). Combat manoeuvres also got screwed, monk became ridiculous with the number of things it got, paladin fused the healer class to it, rogue gains too many special abilities or combat feats with its tricks (as much as I like the beta rogue, it isn't balanced, but that's a problem with more than a few of the classes).
Each to his own of course, but with my 3.5 modified rule set, I cand draw in and use almost anything from 3 to pathfinder, with perhaps some modification. Hell, I even have the books converting second ed stuff to third and 3.5.
4 is a damn gimmick and I gain two points of crotchetiness for bucking the trend. Now roll the d100 table for forum responses as you enter the 30 by 30 forum.
