No, that's not what I said..
I suggested that the Backlash skill be changed so that it won't work unless you can actually get into a back stab position, meaning if you can't get into a position to do a back stab on it then you will just get "Invalid Target" when you point at the target. This to prevent what happened there on that screenshot and for the skill to be more true to the description.
It does say in the description..
"Jump over the enemy, landing behind their back and backstabbing them for [X] physical damage."
If the backside of the enemy isn't clear then you can even end up in front of the enemy, which doesn't even make sense with that description and getting backstabbing.
