According to this statement I have to play on another live server or with an outdated version.
I want your mentioned version too!
The classes are definitely balanced, there is no PT or Burst Sorc that does 1-2k dps more than all other classes.
Well, you lose about 2-3k dps with this change and everyone was complaining about the changes to the sorc.
Also, all dot specializations should make more dmg than a burst specialization on a single target. (For long fights, like the dummy)
