So, I've been playing with a rogue type character and while backstab damage can be impressive it is very finicky.
My main gripes are these:
-Enemies constant animation more often that not made me miss a hit.
-There is no indicator for a backstabbing position. I've been wasting precious AP to find that one spot behind their backs that allows for a backstab and it's even more frustrating when they're knocked down.

So my suggestions are:
- improve enemies hitboxes so that their animation doesn't make you miss hitting them if you're in the right position.
- Create a colored cone behind enemies backs that shows you the correct backstab position angle. Allow it to be seen only by Scoundrels and make it more wide with more points invested into Scoundrel.
