I agree with Hometeam that I wish I could move the FOV out further. You can scroll in more but you start at the max and it's a bit constrained.
The thing that really bothers me is the hitbox. I was doing a witch at first and constantly missing with my wand. I decided to try Marauder and that helped me learn you have to target the mob. I know that sounds obvious but a lot of games like this you can just hold down the key in a direction and it'll whack any mobs that get near you.
Those little shooting scorpions are still a PIA to hit though.
I love the way potions work. The passive skill tree is a bit overwhelming. It's really fun for a free to start game. I think I'll try a few more classes before I go too far
