I think this is a band aid solution that would make the same amount if not more people upset. I feel like the game needs some system to balance the weapons (such as denying Slosher a burst bomb option) but it definitely needs to be less rigid. Basing the kits off popularity somehow would probably make a lot of people upset though as those who wanted to play a kit at higher level wouldn't be able to because of the votes of people who don't even play that weapon.
