I considered backstab an accurate mechanic, if you are attacked from behind you will not be able to see the hit coming right? So having better chance to hit when hitting someone from behind was a good thing, it made sense. What has removing the backstab added to the chance you have to hit an enemy? Height also make sense, for long range having the highground is beneficial, for melee it is easier to attack someone higher than lower. The person above you would have to crouch to hit meanwhile it's fairly easy to swing your sword at their legs, it's harder to defend from melee attack when you are higher up unless you get out of range but then you can't really deal damage anymore.

So yeah.. I will miss backstab :V
