Personally, I'm rather happy with the game as it is, but I still have a wishlist of things that would make my experience in Azeroth even better.
Free server transfers
I would like Blizzard to provide one free server transfer a month per account. It seems to me that many people are quitting the game because they can't afford the $25 to move their characters to a higher population server. Also, quite selfishly, I have some characters that I'd like to move to Zangarmarsh, our It came from the Blog guild server. And while I've paid to transfer characters there before, I really can't afford to keep shelling out the dough. I think this change would go a long way toward keeping people happy and still playing the game -- which is good for everyone.
Unique class storylines
I love what Star Wars: The Old Republic did with classes. Leveling up while following epic storylines specific to your class was a blast. I'd love to see something similar in WoW. I'd like to see what Blizzard has done with the monks' Peak of Serenity and the warlock's green fire quest done for every class. Perhaps we could get solo scenarios every 10 levels with an epic one at max level that might even need a group. I don't know. It doesn't have to be implemented that way, but something that made each class unique would be wonderful.
I want my account-wide heirlooms to actually be account-wide and not just server/faction-wide. I'd like to send cash and bags to my young Alliance duo that I am leveling with my daughter. Or at least just cash. I can see where this would affect the local economies, but we can already move cash around right now by selling battle pets acquired and leveled on different realms.
