Just a small observation from having started to play with the blunderbass:
The last skill of the Azoth Shrapnel Blast tree (Azoth Bomb) does not seem quite right to me.
It’s difficult to aim, always falling somewhere short of where I am, but it’s never clear where. As a result I find it hard to hit anything. The explosion animation is also too fast and as a result looks cartoonish.
The idea is interesting, but I think the bomb needs some kind of projected arc to help the player guide it, and the animation needs to be slower, longer and more realistic.
