Luckily I have it down to a science, and once I move into position behind the enemy, typically it actually costs me 0 points to properly move to backstab.

Regardless, this is definitely an annoying issue and hopefully can be looked into.

We need like, a small 15 degree area cone of view sort of thing that lets us see where exactly we can stand in order to backstab a creature.

I think the reason why this isn't easy, is due to the idle animations of creatures and such, causing the backstab to need fine tune adjustment to get in the right position for such a thing.
