As someone who has just started playing Warrior and have hundreds of hours in this expansion with both other classes.. Its not even close. Since there is no place any person dies if they are properly buffed there is a clear gap to me in the balance.

The only thing the two other classes see is when a Warrior runs a map that can charge Ulti and uses it on boss. Portals are active and warriors are the last to get thought about. I got full kraken minus helm.
