Hi! Thank you for your compliment.

I tried many different heroes, like Ana(Sleep), Mei (Wall), Orisa (Pull), Roadhog (Hook), Sigma (Rock), Sombra (Hack), Zarya (Graviton), Doomfist (Charged Punch).

They all have the problem, that they will stop the ultimate or will trigger the ultimate and I dont have a solution for it yet, that lucio keeps his ultimate at all time and gets pushed back into the air. Actually there is a solution with a invisible lucio dummy bot which is attached, but this is much work.

Ana sleep, Sombra Hack, Doomfist Charge, Roadhog Hook and Sigma Rock are going to cancel his Ultimate.

Mei Wall (To catapult him back so to say) will trigger his ult on the top of the wall

Orisa Pull and Zarya Grav will even trigger Lucios ult mid air

For now, this is why I have only heroes which can push him back in the air - of course, a brig is not as effective as an ashe or doom.
