Ranger up to this was the only one I had success with, found it the easiest much more than  warrior or berserker. Milking shift sprint for all the extra attacks it is worth.   I read that freezing and dominate are very powerful but find  traps, strafe, sleep bomb gameplay much smoother.

Congratz! Abundant use of sprint is really critical for all character types though of course ranger/duelist get to do it the most. I think taking that mindset back to Warrior/Barb can help a lot. Despite those two being the beefiest, no class is really balanced around just face tanking tons of damage.
