I love the idea for this tournement, though there are a few weird things about the banlist to me:
For one, the .52 Gal Deco shouldn't be here. I honestly think this is one of the weakest weapons in the game, just because its kit is argueably one of the worst in the game. Seekers are only good in RM and Inkstrike is just a worse version of Wail. Sure, the main weapon itself is solid, but without Wall + Wail, it isn't amazing. Same goes for the .96 Gal.
I feel like vanilla Carbon and L-3 Nozzlenose D should trade places, as people have already pointed out.
I also have an idea for the banned chargers: what about banning the ability Damage Up on them, as that's why they're so good. It's really rare to see someone run anything other than Damage Up on them, and I'd personally like to see how they'd fare in a tournament setting with that limit. Just food for thought.
That aside, this looks like it could be a blast, and I'd love to participate. Hopefully my teammates will feel the same.
