I don't really see any skills that should be taken out of the game.
Personally, I don't much like the witch doctor's "spider urns" but I'm sure there's others out there that like them. That's the nice thing about how Diablo 3 works: if you don't like it just switch to something that you do like.
I feel that "re-rolling" is far from pointless. Sometimes it's simply fun to go back and just restart for the fun of it. No need for unique stats or skills - the fun is in the play. Twinking I think it's called. That's the reason for low level uniques.
