i'm not one to believe in form over function. min/maxing and optimizing my loadout are going to be more important to me than my appearance, i think. although as a tf2 player who's been spoiled by all the cosmetics in that game this kind of hurts me a little, lmao. i wish that perks weren't assigned to clothes and were just... perks that you can select when creating your loadout, like how most games do it
if perks have barely any added benefit, i'll probably go with what looks better, though
