Cool, I've been waiting for a barber shop style feature since launch. As an ex City of Heroes player it's been very frustrating not to be able to change these things easily (I miss Icon).
My one concern is having to pay cartel coins for something as trivial as changing hairstyle. A full body type or species change I can understand would be a cash option as these are pretty major changes, but I would have hoped changing hair style/colour or facial tattoos would have been available for in-game credits as it's something you may want to do quite frequently if you RP or even if you just get bored of your current look.
I guess it's time to start saving my monthly CC grant...
A race change might be a big one because you have very different options race-by-race.
All other changes are minor. Change a value in a field in the database. Done.
Charging cartel coins for these is absurd, but EA gonna go after the $'s until they force everyone away.
