To those who've quit: What would make you come back?

I like hard AND lengthy.

I don't think any boss should have a timer that lasts longer than 2 hours. I also think bosses that heal are stupid, potential lock is really irritating and damage reflection is only a good idea IF IT WORKS PROPERLY - why does the animation sometimes disappear if the boss is still on DR? It's unbelievably frustrating. I also think bosses should have a better aggro system whereby they target one player only instead of doing the same damn thing to everyone.

Also, stationary bosses are really boring.
