Nostalrius Begins - Quality wow vanilla realm (1.12)

When in stealth and nearing their detection radius, mobs should turn to face you, give some sort of indication of noticing something if applyable (wolves growl, some humanoids say stuff, etc) and when reaching the aggro radius, they aggro you. Currently, they just aggro you when you come close enough.

yeah sucks hard when trying to sap. Also i think sap is broke, always bring me into combat and out of steath, even with a successful sap.
