Id like to see nothing that allows a true advantage over a outfitted BR1 (new player) in anything other than potential organization and cooperation. No damage, defensive or movement bonuses. I do feel this has a viable use just not with direct bonuses. You could however provide a bonus to say resource accumulation or exp and i feel it wouldn't negatively impact game play but it needs to be fairly minor and the progression itself needs to scale so that both small and large outfits have no real advantage to unlock it. Mostly cosmetics is where i feel like this lay.
