Hi!
I've been playing the game for some hours (around 140). Not a pro at all.

I have 2 problems.

The first one is that potion doesn't feel like it's working correctly. I mean that you have to be not using a skill to be able to use a potion which break the pace of the game. When I want to use a potion I just stop moving or do anything to be sure that I can use my potion.
In other ARPG, you can use potion whenever you want.

Second is when I die, I die in row. In D3, you become a ghost for a few second which allow you to disengage, rebuff then go in. You can control the fight.
Right now just feel annoying.

Good luck Dev and what other players think about that ?
