Brushes, Dynamo, Splatlings, everything that I used to main. The Inkbrush has a lot of potential for redemption with some amazing kits. The Octobrush's kit is a bit iffy but definitely salvageable if Autobombs turn out better than expected, since Inkjet is pretty nice on it. I really don't like the Dynamo kit but that means there's only room for improvement on the Gold, no? I love Sprinkler on the Heavy but I'm not sure about Sting Ray on it (more optimistic than with the Dynamo though.)
Other than that, I will definitely main a beakon weapon for the sake of beakons. Dapple Dualies look promising especially with Suction Bomb Launcher but I'll have to see how it works out.
The Splat Brella scratches my support itch and it looks awesome. From the ink tank indicator in the footage it seems to have Sprinklers which would be perfect for me, but maybe we'll get a beakon variant and I can hit two salmonid with one stone. Why not both? Real talk though, the Brella has to try pretty hard to disappoint me.
