Some ideas:
(credits to whoever said them)
PVP - 5 person free for all, first person to 20 kills wins.
PVE - Survival mode. Sort of like zombie apocolypse. There are waves of enemies. If you kill x amount, you get a prize.
Maps that elevate- you know how all maps are flat and you just run around? Would if the land elevated and you could use stairs or hills?
Attacking pets- 'Nuff said
Pet quests for all levels- 'Nuff said
Vanity rewards for all chapters- 'Nuff said
