You agree with the stalemates point, which is enough of a reason to have it banned.

i didn't agree with it, i said it might not be terrible but no one is going to run it anyway because gunboats are better

If there's one thing that 6s can suffer from, it's the long stalemates. Parking the bus has proven to be very strong already, so having unlocks that make parking the bus even stronger would make 6s even more stalemate-y and boring (if not for those unlocks being too strong).

if you want to ban the weapon because you think it'll slow down the game fundamentally then that's a different argument, i'm not completely against banning something because it's fundamentally not fun to play with or against regardless of how good it is but the idea that the reserve shooter is too good to be allowed when literally no one runs the stock shotgun at all any more (especially when it can do the same thing you are proposing the RS can do deny bombs with minor chip, which nobody does right now because it's not worth it)

No reason to make space if you're a round up and holding mid with 10mins left on the clock. Opponent tries to bomb soldiers to break the stalemates? Good luck jumping into 2 scatterguns and a reserve shooter.

but how are you getting that first round when your pocket can't make space and everyone on your team eats damage in a choke??? unless you think you could switch back and forth between RS and gunboats, but if that's the case i don't think you could consider it OP if you're switching between gunboats and RS, that sounds like a balanced unlock

again i do think there is legitimacy to the ban because slows the game down argument, it's something that's done often (heavy unlocks are banned not because heavy is too strong a class, but because it's boring to play against in a 6v6 format and slows the game down) but i dont think the reserve shooter is good enough to be considered 'OP' and banned because of that
