I've said it since before the game even launched, but we really need to be able to customize our main Hero. As it stands there is really nothing connecting me to the game. That is why I haven't played much. It is a decent RTS, but there isn't much MMO in it other than being persistent.
Being able to get trinkets, weapons, armor, mounts, pets, etc. for my hero would actually bring me into the game, and want to play it since I would feel connected to it. As it is now I just have a bunch little pixels running around doing my bidding.
