Been long since I played a Monk, so dunno how they fare in comparison to a Fighter, I think Monks should have the best saves in the game, but they also have a decent magic resistance, so to counter the fact they are a powerhouse versus creatures that rely on magics and special abilites that allows a save, Monks should be a bit worse (compared to warrior classes) at AC and the amount of physical damage they can constanly dish out.
Since the only thing Paladins lose when compared to a Fighter is Grand Mastery, and they get extra saves, protection from evil (very good and useful spell all the way through the game) plus some other spell choices later on, I think the +2 on all saves for Paladins is a bit too much, +1 is fine.
Just my opinion in the subect, though I'm completely ignorant in regards to KR.
