Perhaps lag in groups has always been a thing that gets pretty bad, but it seems lately whenever we have a decent sized group going it soon becomes very lagged. The weird thing is that some mobs seem worse than others. Maybe some mobs are doing something that's causing the lag, or perhaps when they damage the entire group at once it causes a large set of updates ie via msdp.CHARACTER_HEALTH to be sent out.
Do we have any idea what the cause is here? Is it too much msdp chatter? artifacts? just something you have to live with after a group reaches a certain size? Is this just my perception, maybe it's just my system getting slowed down.
