Game Mechanics: More than 4 npc's shouldn't be able to attack a target at once

yeah, I think you are on the right track with why they had implemented this. they had a lot of problems with people crashing and zones crashing towards the end of closed beta when they started doing all these major events that involved massive amounts of players casting spells or getting hit by spells/mobs.

i know for all of closed beta ALL AoE spells for instance would hit ALL mobs in the AoE. I also know this was changed either at the end of closed or sometimes before launch so that most spells were capped at 4, unless they had a longish recast time.

For the snarky people who are crying about implementing this on P99. Can you tell me when this was first implemented in classic, when it ended, and how exactly it functioned throughout? All the contemporary sources conflict in many meaningful ways to come to any good conclusion on how it actually worked.

I also do recall there was a way to bypass this limit for players pet that involved the pet classes spamming pet back off + pet kill. if all the pet users were doing this it would somewhat bypass the "limit of 4".
