Read both Xanamancer's and Newbzorz's comments. That happens a lot in these comments. Engineer is more straight-forward to play, that is true, but which class is the best is hard to say. They all play different.
The bug fix will prevent it happening AGAIN, but unfortunately, if they are already saved as being scrambled before I fixed it, they will stay in that pattern. They should always go back to that though from now on. Everyone should make sure they have 2.2.6.
Ok, I think I finally fixed the scramble bug. From here out, your skills should always revert back to where they started each battle. Sorry for the issues, that bug is my bane.
Difficulty on Rufuss has been lowered. Just a tip with Juggernaut, your Adrenaline Rush sucks up a LOT of damage (and turns it into power). Use that when you are expecting a big hit.
