I am dual boxing mages and have 3 questions:

1. Every like 5 minutes my slave will stop following, what causes this? How can I fix it?
2. Sometimes my mage isnt faceing the right way, not to bad of an inconveniece to move, but Is there a way to fix this?
3. My mages are very squishy and its hard to get away from fire, What would be the best healer for 2 mages in pvp?
thanks
