When I was levelling my demon hunter I was able to use vault to quickly get away from an area where damage was happening or smoke screen to break freezes and jailer cages.
I've had some difficulty with arcane, jailer, frozen as they can really stack up quickly.
I do use ignore pain to great effect, but that doesn't help against everything.
What can I do on a barbarian to counter the various elite affixes? Which will break freezes and jailers?
