Free to play members should not be limited on character customization like they are. It takes away from the role-playing aspect to be limited to the being just a plain human/cyborg with the only alien species available is Zabraks (available without spending Cartel Coins). They should have the same character customization that is available to a brand new subscriber making his/her first character as well. Also, they should be able to hide their helmet slot to their desire, show their legacy name, unify armor colors, quickbar amount, etc. All these restrictions to FTP customization are unnecessary to have.
I agree that the restrictions in Free2Players seems largely arbitrary (almost as if Bioware felt they needed to have restrictions, but had no idea what they could restrict). Besides, Cyborg isn't a species, it's a technological addition to humans and shouldn't be treated as separate; ideally, cybernetics would be a customization slider on every species.
Also, player feedback important? Is that before or after they've ripped the patches apart on the PTS and you roll them out as is?
