On the Auto-attack problem, I've been beating that dead horse since the game came out. My suggestion has been the same and taken from other mmos as far back as EQ frankly:

Pet modes: Have an option to set your avatar on passive or aggressive. If passive, it will not auto-attack. Problem solved. If aggressive, it will auto-attack as it does now.

I hated summoning my avatars back in the old dynamis days after the blm had done sleepgas on big pulls and I had hate from curing. only to summon an avatar and have it float off and start waking things up and watching blm drop like flies. Though.... I was a master of MPK in those respects
