first of all sorry for my english, i will try to write the best i can :)
I was playing today with complete normality since 18:00 to 21:40 (GMT+1) with my barbarian.
The setup of my barb is this:
Frenzy -> Sidearm
Revenge -> Provocation
War Cry -> Impunity
Furious Charge -> Dreadnought
Ignore Pain -> Ignorance is Bliss
Wrath of the Berserker -> Insanity
Tough as Nails
Nerves Of Steel
When i was in the arreat crater level 2, two times i got stuck (and inmortal, with 0 health and no die), the champion could die because the Enchantress was doing dps and the proc of my ring was helping her. I couldnt use any habilites even the portal (only use potions)
. I had to invite a friend, exit the game and enter to pickup the loot.
The first time i did the elites and champions from the first part of the act III to get the 5 nephalem, and go on to kill cydaea, but in another encounter again the same (and again in the same instance of arreat crater lvl 2), stuck in combat with a champion, inmortal, unable to cast, only to use potions and my Enchantress and my ring did all the job. (and again a friend with me to maintain the loot while i exit and re-enter the game).
I hope this would be helping for the devs.
