Anyway, some more ideas
Replacing the Scattergun- Nailgun
Back from TFC and the beta trailers. Shoots a steady stream of nails (3/sec, 12dps). 12 nails loaded, carrying 36 extra. Valve said they wanted the Scoot to be more useful in Dustbowl-style maps, I think this works.
Replacing the Bat- Super Slugger
Like the regular bat, only it bats enemies far away while doing minimal damage (like 10-30 HP). Sorta like the Pyro's compression blast only it only knocks enemies away, not Rockets/Nades/etc. Would be good for clearing enemies off points for capping.
