A hero that can replicate the items around the map (jars and boxes), maybe creeps but provide debuffs/damage to the enemy that attack or steal from them at random what the jar/crate could have rewarded and line of site for the player placing them
An all melee hero, fun leaps, lots of in your face chaos, don't even make it a humanlike character since no guns. Eats bullets maybe or melee hits reduce ammo? Spit balling here
Hero passives
With all the verticality I feel like a character that can stick to walls would be pretty cool instead of floating in the sky
A character with the ability to grab onto the sky rail and hang on any side, place traps on them
Not sure if the design behind the game was to avoid heroes with shields but I haven't noticed any yet
