Hi as some one who has backed over 30 projects on kickstarter I have suggestion to draw in more people...The Carbon tier would be better if you would add beta also to that paying 40& so 20$+ just for beta seems a bit much you might want to add alpha insted for the 40$ tier to draw in the people.
Also 20$ for 2 month membership and nothing else is a bit to much for indy mmo.
Also one question is the game free with only subs or what there is no digital copy in any of the tiers.
