An in game barber or doctor that you pay say... 100-200k to change your appearance or just your hair? of course the game functioning is more important but the one thing about DBO I never liked was being stuck with a look I grew tired of.
Leveling is a long enough process and when you get high up you do want to eventually change things up a little? like in xenoverse you can use shenron to grant the wish but depending on the difficulty of the dragonball hunt that could be a bit extreme so I do believe an in game npc would be the best option.
What do you guys think?
