Periodically, in larger guilds like mine, there will be a mass [Player has come online/offline] spam, causing a MASSIVE lag spike, that has wiped my guild muiltiple times. this has been going on for awhile now, and has been an absolute nightmare.
The same has been happening to my guild as well it’s getting to the point where people are leaving because of the spike. It causes M+ keys to be bricked and raids to wipe.
The main reason this isn’t being looked into there isn’t many mega guilds left on wow. I’m not sure how it would even be solved. It has to do with the amount of players online in guild and switching between characters. We have 80+ players on each night, and it vomits on us on a regular basis. This bug needs to be looked into and solved.
Personally, I think they need to put this into the game instead of character names in guild. It would clear up a lot of issues they are facing. then they could store that information on a place and link it for fast sorting.

I think people have gotten used to the idea of WoW always having some issue, so most just resign themselves to yet another problem.
