I have been levelling in Darkshore for some times and I noticed 2 problems with mobs:
1) when you attack a mob with a ranged attack, the mob charges you. Often, the mob runs past you (instead of stopping in front of you) and this forces you to step back or rotate. This is not what happened on retail.
2) when you aggro and wound a mob and for some reason you flee, the mob keeps chasing you forever, instead of stopping following you after some distance.
