That's my build, and I completely decimate rifts on t5 until I come up to a yellow elite or rift boss. My damage is seriously lacking against single targets, what skill should I change to fix that?
Also, I don't have a mirrorball. If I do get one, will it help a lot against single targets? I heard mirrorball magic missile(fire) destroys single targets but not too sure how true that is.
Note: I have about 120% damage to fire, so I'm not sure that a non-fire skill is worth using.
