Accuracy from a back

All have misses from a back? Though there have to be 100%!

Your mainhand attacks (this includes all of your abilities) have a base miss chance of at least 5% versus and opponent of equal level. this increases by another 0.5% per level difference vs opponents up to 2 levels higher than you and 3% more for opponents 3 levels higher than you.

This means you have a miss chance of 9% versus an NPC that is 3 levels higher than you (this becomes important for endgame PvE content, as basically everything you fight will be equivalent of level 63)

In addition to that, NPCs can dodge while stunned and/or while being attacked from behind. I have had a stunned NPC dodge my Backstab before and it sucks, but that is just how the cookie crumbles.
