Ravamp/enhancement of PvP
They are already supposed to have a team working on this (as part of the outposts)
Balancing/rework of ranged combat
They have said they will be looking into this though personaly i see nothing wrong with it (im 101 1h and 2h) , sure it gets harder to solo the higher you get but thats the same for all combat skills , (i got my lvls through solo Kiting clopper in WoM not sure this still works with the lose agro feature)
Event tools
There was a big announcement and a trianing day (?) for the last set but nothing seems to have come of that , the majority of events since have just been standard escort type's , maybe the GMs life has been made easier but theres been no impact ingame as far as i can see
Rites
There is supposedly a mass (70-90) just waiting to be patched in , just what the hold up is who can say (the devs obviously -but they dont talk

) , some of these Rites are much needed ingame -im thinking high region tele ports etc , so this gets my vote
