Eh, I'm thinking towards actual real updates for the game to get back player interest again.
Skins only cater to people already playing the game. They 100% need to scrap OW+trust factor and start over again with VAC. Either change how VAC works or scrap that too and introduce VAC2. We are at a point where new players are going to be instantly uninterested in the game due to the sheer amount of cheaters/spinbotters (<-which no other game has btw) and cheaters can just buy a new high trust prime ready account for <$5.
Also, they need to add active duty maps to scrimmage mode. Right now, it's pretty much pointless to play scrimmage unless you are doing challenges. This also turns players off, as casual is pretty garbage by itself.
TLDR; New Anti-Cheat that works, New server browser, new Demo system and a shakeup in the map pool and Viola, You have a lot of new interest in the game.
