makes sure I get 10% of that because of all the wasted space on my hd being used but useless squad skins

Your squad wants 2 skins. If everyone in your squad pays 5 bucks thats no biggie,
Suppose the maws want a "squad skin" for every plane they fly and each "of the maw squads wants them a bit different.
They all chip in .50 cents and now they have 25 oftheir skins plus your 2 27 so far with just 2 squads, then the aks, and the other hundred or so navy/ marine squads.
Hell my previous squad 3./JG 2 would need a scheme in each 109/190 and maybe seasonal skins. We all chip in 2 bucks np.
Adding money to it doesnt make it any less bloated or pointless.
The potential is there for hundreds of variations.
