Things i would personally add :
xp lock - handy for pures
adding morrigans to revs - not sure if this is already added but im pretty sure it isnt
dungeoneering - me personally would work on a unique way of dungeoneering, but whist your doing that adding some npc in some closed off area with a teleport to that area, and just kill the npc for dung xp whilst you work on a unique way.
hope you take these things into consideration as i sure alot of people would like these added, thanks
