Everytime a guildmember logs on or off the game stutters/lags for a second

This is also reported by other players in the comments on the Twitch App Website for the addons.

The micro stutter stops one from reacting for a second, deadly when boosting or in a difficult aoe pull with the multibox team.

In active guilds, there are players coming online and offline every minute, so it's a constant lag issue
