A Mars/Pantheon style teamfight area control hero

[vinyl5001]

How about an area control hero with a Ultimate that restricts movement inside of it for enemy players with walls?
Sorta like Mars or Pantheon. Could be either a support/tank hero that locks enemies away from your team or a melee focused fighter that takes advantage of closed quarters themselves.

it could be cool to have a melee based hero that has like slowing zone abilities or stuff like that, idk if that's what you meant

Doesn't Kelvin already fill this niche with his snowglobe ult?
