Fix the agro!

[Greul]

Some mobs at same level as you agro from 20-25 yards(like the +7 ones) normal agro is 30y+ because 30y is the optimal range for casters,also the ones below you with 7+ level agro from like 10 yards and is supose to have max 5 agro yards in that case.
I played wow since patch 1.0.1 till 3.0.3 and I never remember mobs who will chase you till the end of the world this "thing" will help ofc range players like Lock/Hunters/Mages (the kite) and in the same time will produce imbalance too.
The reset of the agro also is fucked up,if u hit a mob and run away 100+ yards you are still in combat if the mob didan`t die and fight with other players (you should get out of combat if u are 30y away from the fight).
