1. Wait until your avatar catches up to you before hitting Assault? It is not that hard.

2. This is not a problem, this is a shining example as to why SMNs are so great at what they do. Having the avatar attack a mob that has aggression towards you is the pinnacle of kiting. Otherwise we would be endangering ourselves to have to hit assault each time we resummon an avatar.

3. Ok, you got one problem right. 1/3 "problems" isn't that bad, but isn't that great either.

Only 1 thing needs to be fixed, you probably have not been a SMN that long by the looks of it. Besides, what slept mob would have hate on you anyway?
