- Crafting : do it the way Vanguard did it : a whole crafting game, with crafting skills, crafting equipment, crafting quests, and actual player skill required to make an item (you have to learn how it works, its not automatic).
- Secret passages : please add some !
- Underworld : the whole map should exist as an underworld, with different levels of difficulty/dangerousness
- Living world : pretty much all MMO worlds are dead. Nothing ever changes in them, it's sad.
- Don't go the items > all way. If PvP success can be ensured by getting the best equipment, then it's not worth playing. If your whole equipment gives a 10% stats bonus it's ok, but if it gives 150% then PvP gameplay is dead.
