What happened to the movement of mobs?

Lately in this patch ir've noticed that the mobs movement whem i am tanking them are all most out of control.

Senarior:

I normaly could just move back a bit and they will folow me.
But now... when ever i move back they go around me, and some times behind me.

I feel like i dont have the same control over them as i useually did...


Any one else noticed it?
