So first of all I'd like to say I JUST LOVE THESE SKILLS!
I've tryed all skills and all of them are well balanced, working, no bugs, and just everything was perfectly smooth.
As a damage dealer I felt very strong. I actually felt like a real damage dealer, but not for multiple targets (well that's because I'm axe champ and axe champs are focused on single combat). Anyway this axe champ build is great for killing bosses and mobs.
As a tank I felt very weak. Single mobs is okay for me, but multiple mobs like 6 or more is too much. I can't last long when I'm surrounded and my AoEs doesn't save me. Well I think it's just perfectly balanced class, if I would want to be a tank then I would pick a knight.
The last thing I can say is these skills are perfect and now I will be just waiting for the critical stat update where it will be shown as percentage.
