Just your local person deciding to play a ranger to be weird.
Anyway, here's a very stoic changeling ranger.
I accidentally made them look more like agent 6 from generator rex than I meant to, but I mean them to be more along the lines of a James Bond type character, just. Being a NB changeling instead of a human man.
Instead of having normal armour, they have a suit, and the suit getting fancier makes other people not really want to damage such a cool suit, and also motivates Bu to avoid the damage more entirely. Just a neat way to reflavour armour.
