Somehow I can't help but think that it's the inception of the NPC/Monster Collsion mechanics that everybody begged for that's causing the added stress. Collision mechanics are very resource intensive (hence why they chose to make it absent with PvP). The devs had even mentioned being reluctant to add collision due to server demand. Now that it's there with this recent update, and coincidentally server load has once again failed to maintain Phase mechanics, the setback is pretty obvious. I can't help but think that perhaps ESO should just drop the Collision mechanic system. Sure it's nice to have... but many other MMO's have opted to not implement collision for the same reason.
Thoughts?
