I do quite a bit. I got my crafters to 70 within the first month of the expansion being released. I maxed my gatherers before that. I finished leveling my last job to 70 during Patch 4.1. So all of that stuff I've done.

I do go back and do all the sidequests in an expansion because I like clean maps (need to finish SB - still have some left in Yanxia; also should finish the Postmoogle quests at some point)). I've maxed out all beast tribes. I occasionally join Hunt trains on my server (not that often though). I do roulettes to cap.

Most of my time now is spent raiding. Or doing Extreme primals for mounts. Since I have so much maxed on my main, I tend to play alts, I have 2 in HW's main story right now, and other at various stages in ARR.

I usually do a lot of relics to keep myself busy on my main, but I opted out of Eureka. So unless I do old relics, that's not something I fill my time with.

So there's quite a bit to do, but repetition can get boring so I have to mix in alt adventurers so I'm doing something other than "normal endgame stuff".
