Current character customization system is really not that difficult. It has quite limited posibilities. Try to create a bald guy for example and compare it to other bald guy someone else created. I bet they will look like brothers.
Plus you can't make a goofy looking characters anymore.
So why can't we first pick a specific type of nose/mouth/eyes/ears, then select a skin condition or texture of that area and then finally actually shaping it up to our liking? Would it be too time consuming for developers? Btw i dont mind that much if it stays in the game as long as they fix other more important features.
