Hey,
It sometimes can be a pain when you are almost facing the correct direction to actually in theory "hit" the monster but in fact you are slightly not facing precisely enough to actually strike it which isn't annoying but sometimes a bit long winded when melee'ing for hours lol!
What about if when a mob stikes the character something tells the server or something that you were hit in the "Front" or the "Rear", this way any mobs that are told they hit you in the "Front" will be hit exactly back when you hit strike till it is dead, instead of having to re click and adjust slightly to actually hit a monster which was in theory practically facing your front hitting you.
Don't know if that seams feasible!
Take Care
