Been playing this game. It's good, amazing for a free to play. I like the fact it's not "pay to win" like so many "free" games.
I am struggling with Act3 though. The difficulty ramped way up and I'm regretting some of the choices I made in the tree. I also kinda wish the camera was zoomed out more and there was a better UI and little bit of character customization at the beginning.
It's definitely not a game for new or casual players to this genre. I enjoy but it seems very specific, you really need to know what the hell you're doing because the game doesn't tell you at all. It'll hold me over until I get D3 on the PS4 next year.
