When making Lucio, I tried to stick close with what make him so good in Overwatch and transfer that all to Heroes. The issue I found (which is why I made the modification) is just how powerful movement speed is in Heroes. To grant nearby allied heroes a 110% movement speed buff in Heroes would be insane, especially with certain heroes in the game. To balance it out, I made the other Crossfade bonus mana to reinforce his support capabilities and made the movement speed buff an ability to stop it being super op. Anyway, with that disclaimer out of the way, lets begin!
Lucio is a mobile support whose main power comes from the constant aura effects that he can apply to nearby heroes. This means that positioning is key on him, setting yourself up in a position where you can affect both your tanks and your back line.

Maybe add a talent that lets him go over terrain and unpathable areas, and call it "Wall Ride" this would help out with his positioning and escapes
This Is a great concept as it doesn't copy his exact kit from OW
