Looking at some old zones I haven't done before, and on the EQR page for the zone: https://voa.eqresource.com/questsnpcsepulcher.php Besides the standard Merc/Partisan/Mission quests you see for all other zones, there are a bunch of other quests listed. What are all these for? Are they associated with raid activities?
It basically gives you options on how you want to collect the pieces for the main quests, so if you hate certain types you can skip, but generally you would do the best currency per quest to get it done faster
