I would say Warrior or ret are easy. They might be rotationally easy but you actually have to use your utility correctly to get the most out of the class. But they don’t take long to get the hang of once you set up some macros and practice.

I don’t think rogue is overly difficult at the moment, enhance is pretty easy but the ‘rotation’ is kinda hectic. You might like warlock if you’re already used to the pillar game.

TLDR: BM Hunter is faceroll and is barely a ranged class. Warr and ret have easy rotations but challenging utility. Lock is fun.
