Lemme add, PvPing--ALL THE TIME, siege weaponry, owning parts of the map, wars to own those parts of the map,non cartoonish, diabloish, refining anything you want to add stats to em, as far as possible without breaking it, etc, etc , etc.
One of my main problems is WoW and the like are VERY CHILDRENS cartoonish, they dont have PvP all the time, its seems like over rated commercial BS(have a friend that plays all the time) The HUD is completely overcrowded,the whole feel seems like it was crafted for child gamers.
