I have some idea:

Barber - you can change your fighter hairstyle and beard. I think is boring, you have the same apperance. sometimes I want to change my fighter style.

Weight loss and gain - maybe you could have a special diet. and you change your original weight. it's not weight cut.

one account, more camps - you can have more camps, but it would be more comfortable, if you could have more camps in one account.
