Zoom, I am not sure how an orange spawn just agro me, at first I thought was a rogue npc. Once I target him the rest of the spawn lock and target me. Another question, before the patch if we attack a spawn of npc's (orange) only the same name and type would agro the player, now its the whole spawn. I am not 100% sure (and with randomly orange spawn aggro, I am not going to do any more testing) but if you are under 1 km away from spawn and trying to kite a single npc from the group of spawn. Even if they don't have you lock or if you don't have them lock,the 30 seconds doesn't work they still keep following you. Before the patch npc (orange) same type and name work as one, after the patch they whole spawn counting respawns work as one, Is this a bug or a change to the AI ?
New: Improved NPC AI - Their movement should be much better and responsive, most notably they won't stand still if you are moving. New behavior rules have been also added: while an NPC is aggressing you it will follow you without considering any range limits. However, it will stop chasing you if you move 1km away from it, or you stop attacking it for at least 30 seconds. (When you're trying to flee the latter will probably happen sooner.) Note: the 30 seconds rule only works for orange (passive) NPCs, since red (aggressive) NPCs will re-engage you all the time even if you are not attacking them.
Patch Notes doesn't say anything about the change to the npc name and type.
