Aran likes the middle of the room. He stays there unless you interrupt his arcane missile. You can interrupt the rest, but if you interrupt that one he starts running around and melees the guy that his AM intially targetted. His melee is almost useless, but it pulls him out of position and that can be a pain.
Thats because you locked him out of all 3 of his magic schools, fire, frost and arcane. He can't cast.

A much better reason not to interrupt his arcane missile is because the mana is already spent when he starts casting. Aran is a race between his HP and Mana. If his Mana goes lower than his HP he sheeps everyone and heals. When he starts casting Fireballs and Frostbolts the mana isn't spent until he finishes casting so interrupting those keeps him from using mana. With the arcane missiles the mana is already spent so let him cast away for 3 or so seconds because he won't be doing any Fireballs or Frostbolts in that time and it gives your spell interrupt cooldowns time to reset.
