Make Weapon Skins/Camos Applicable Faction-Wide.
Disclaimer: I will use the terms 'skin', 'camo', and 'pattern' interchangeably
Weapon skins that the player pays for should be applicable to all weapons of that faction (or of that weapon category). It is very anti-consumer that the only way a player can get the same skin on a different weapon would mean they have to purchase said skin multiple times.
To give an example of how I think this system should work, if you acquire a skin for any Aeros firearm, assuming that same pattern/skin exists for any other Aeros firearm, the player should receive that as well.
Or alternatively, if you acquire a skin for an Aeros pistol, that skin/pattern should be free to apply to the Meridian & Sabrask pistols, assuming said patterns work are compatible.
