I am really trying to decide witch one to pick for next season, played with mage this season and I am kinda bored. Not aiming for nothing that great, just a lil fun. I Love chaos bolt and Destro mechanics but I feel a lil hopeless against melee. I like Rogue playstyle and how useful you can be in BG's sometimes changing match result completly, but I tend to get tired with melee fast. The mage is a lil bit of both actually, but with lesser sneakeability and more melee control.
I know that is something only me can decide, but all your points may be helpful on my final decision.
I was also considering leveling a monk, something fresh and diferent, however, I am kinda busy and the lack of time plus all the slowliness of leveling made me give up.
