"don't remove the jetpack pls it's fun

"
It's fun for the RED team, yes, but a hassle for the BLU team. It grants an easy way to rebel, quick bhops, easy access to areas BLUs without air propulsion methods cannot reach and the ability to make some minigames absolutely trivial.
It'll probably be restricted to needing ammo boxes to restart the charging process, or get the same treatment the Gas Passer will eventually, and have no ability to charge it on the RED team.
It's a good thing we weren't stupid enough to revoke crits from BLU team, otherwise the next few weeks would've been utter dog shit to cope with.
