Aggro, Casting Mobs, and a pink tutu

1) How do you make your NPCs aggro on sight? I've given them faction, given players a base negative faction, and even slaughtered those mobs (while being given the 'Your faction cannot get any worse!' messages) and yet they will not attack me on sight. How

Mobs will NEVER agro a GM, or anyone with higher then "0" status

2) NPCs with spell tables seem to like to cast their spells over, and over and over...can this be stopped, so they only cast at certain intervals? And can I prevent those casting mobs from having more than 1 pet (I've seen several of the same pet)? And why do they look like they're doing jumping jacks when they cast (players too), and can THAT be fixed?

Edit the mobs spell list and just take pet spells out, as to casting over and over I am not sure what you mean, if you mean every time yo zone in there casting, that is becuase if you zone out of the zone the mobs despawn, when you zone back in the rebuff themselfs, the zone is only up when there is players in it.

3) The regen rate for players and mobs is insane. Can I change this, whether in the database or in the code?

There is already several posts that answer this one and explain how to change the regen rate.
