I like the idea of endorsements, but they never really feel like endorsements. Athletes wear their endorsements on them when they play, and racers have their entire cars designed by their sponsors. We could have the same thing going for the pros. Have stickers at the appropriate places. This is simply a presentation thing, not that it would actually have much of a gameplay value. We already can see the stats of people that get us. Either go for stickers or make some kind of physical add-on.
ROF silver + gold should always add an extra minigun for the gunner. (So he ends up with three miniguns in total.)
