Must pay gold for crew name/portrait changes? I understand paying gold (real money) for 'bling' options like paintjobs and decals. It lets people show off to their peers. 

Obviously pay-to-win (ish) features like magical ammo, and (pay-to-save-time) options such as 100% skill training are fine to charge gold for as well. 

 I even can turn a blind eye on the gold fee for removing 'complex equipment'. Again, that save the player time in the grind to get more equipment. 

Fiine...fiiiine. 

But..

Charging us to change the names and portrait of our crew members? A minuscule detail that bears no effect on gameplay, and isn't even visible to other players?

Where's the game dev reasoning behind this?
