Maybe I'm on at odd hours, but I haven't seen much of anything for live events.
I read a while back about players that would stumble across a NPC who would ask for help, players would interact, etc.
I remember a live event in EQ1 where waves of skeletons would appear and wreak havoc. The boss would drop some nice Lore loot. Eventually the spawn points were camped so everyone could get their share.
I'd like to see something like that again, but in each scale of zone. Meaning, in Antonica/Commonlands level 10-20 mobs come out. In TS it would be levels 20-30, etc.
At least some live interaction with GM's would be interesting and break up the grind. Maybe something that involved lore, timed race, scavenger hunt, or guess what's in my pockets.
How about you?
