I had to recently turn the SmartAggro system off, because they were killing my raid content with an exploit involving the code..
How it works is a tank steps in with DA on, the mob attacks the tank still.. Meanwhile the rest of the raid just stands back watching and sending their pets in.. The Mob will never turn to kill pets.. A DA should drop the player to the bottom of the npc's hate list. Turning to kill the pets, then back to the tank..
So I had them switching between discs and DA over and over with pets as main dps in every raid they did.. No use for melee in this scenario.. I had to just turn it off back to the old system where pet agro wasn't smart...
The irony is I was trying to get this pet agro thing fixed for a long time, it just needs to be fine tuned I think
As always devs i'm in #kmra can tell you exactly how it works on Live can come pick my brain any time.
