I think adding one setup tech for cowboy would be great, I feel like he can get powercrept with the amount of stuff ninja or even wizard have. Something to do with the gun maybe, throw a cigar or a bottle and you can choose to shoot the opponent or the thing. Bottle can work the same as Hol Horse in jojo HFTF where glass shards fall off the sky. And maybe cigar will have a hitbox similar to magic missile that explodes when you shoot it, making new combo routes
It's not much, but it can keep the opponent from dodging cowboy and keeping the game more grounded
