That's something completely different though...
Unlike the voting options, which affect every single player equally, not (being able to) selecting a kit offers some unfair disadvantages for individual players, which could have a huge impact on the game.
For example, let's assume auto-kits weren't a thing: when you'd join a game the second before it starts and have no kit selected, players having a kit enabled would already have a (slight) advantage over you simply because you were unlucky to join a game at the exact moment it started.
And I know some kits are totally useless depending on the chosen voting options, but I think we can all agree that this issue simply needs a fix as soon as possible... All kits should be balanced, no matter the game mode.
