Ah I see, we've had a lot of feedback saying that the early game is far too difficult on Wizard when playing on higher mastery levels.
There are a lot of changes coming next update to address this (the dev logs go into detail on them) but the high level is:-
- Increased base attack speed for the Wizard
- Mastery Levels will give enemies per Speed and HP per day instead of a huge boost on day 1 (so you will have more time to get better talents before enemies overrun you)
- Wizard (and all classes) will have access to more powerful Traits as they level up
