This is a pretty cool idea, but repairing your gun can be easily done by finding a trader who sells minerals, it encourages players to sell their minerals or start searching for players in the trade tables, simply buying the repairs for your gun just sounds too simple. I also believe adding a free gun skin won’t attract a lot of players to buy VIP, because right now a majority of players are mainly look at the ultimated revive, free gun repairs and speed boost, but it would be a great addition to at least attract a couple of players, but another problem rises, what happens to players that don’t have the gun? It should include everyone, even new players.

I snatched this from Aereos V.
But for the free hat, I think its fabulous idea to add to vip, who knows? Maybe if there was a small contest to see which players can make a hat for VIP might interest players.
