Try Summoner. There is virtually no rotation, just put some DoTs and spam 1 or 2 spells over and over, refresh DoTs etc. There is a stack mechanic (Aethertrail) that is really simple to do too. Plus you get a pet that most likely does more dps with autoattacks than any of the spells you cast.
Bonus: you automatically get a healer too (Scholar).
Ah, also most things are instant casts, so no worries for cast times/movement.
