Lets say all your points are implemented. Why would I buy this expansion ? 1. Different zones. 2. Vague. 3. Different player race. don't care 4/5/6. 7. Don't care. healer merc is all I need 8. Don't care. 9. Don't care. 10. Vague. So really the only selling point will then be new zones, I have more than enough to keep me occupied by leveling / progression in older content 3. New player race, that would mean classes, dialogue for epics, new starting quests, guild masters etc etc. Keep in mind that most of the npc models have limited animations. Almost a whole expansion worth of work just for this point. 8. Marketplace mounts becoming irrelevant since you can buy different ones with plat. 10. Bugfixes should not be expansion bound.
