Unfortunatley the mob pathing is a bug introduced with patch 3.3. Blizzard claim to have hotfixed it but it has not been fixed.
The best we can do currently is to either stun the mobs which then seems to cause them to line up correctly. Or you can slowly backpeddle until they are possitioned correctly. Its a pain but its is important to ensure mobs are in front of you.
