This is by no means standard in MMOs. Usually, so long as you're kiting (occasionally firing into the mob, then retreating) you can hold aggro indefinitely. Just for fun I dragged a boss clear across a game world doing this. I often play squishy, lightly armored healers, so I'm well versed in mob psychology and kiting.
I believe the problem in ESO may have something to do with our old friend, Phasing.
Not lazy programing despite what people may think programing a set of "laws" or paths and rules for an AI is not that simple. Most mmos do this as one of the post mentioned to prevent those who round up a WHOLE area then kill them. As for being hit behind a wall, i have not had this issue, but i have also made sure i was fully behind the wall.No kiting allowed past a certain point. It's lazy programming just like how enemies can shoot you even when your out of line of sight of them through walls etc.
Yes it would allow an team to pull loads of mobs with the tank and then aoe them down, or somebody running away pull 30 mobs out of the area.Not lazy programing despite what people may think programing a set of "laws" or paths and rules for an AI is not that simple.
