The only way to get them to listen is to vote with your wallet and NOT preorder until they add the things you want or you are only helping continue this insanity. Don't worry, no figure sells out before release anymore anyway. Of course though it's your money and your choice, just saying if you want it change then don't order now.
I like Maul a lot, despite not loving Ep.1, and Im STILL on the market for a good Maul. So the fact that I wont be buying this... Im doing my part at least to show them this is severely overpriced.
Same price I paid for my Joker 2.0... which came with a FEW items. A few being VERY sarcastic. It was stacked to the 9's, and was like $10 more than this. No way could anyone justify this price for what you are getting.
