Swain is missing some Birbs imo.
For how many Ravens there are in his Splash art, there aren't that many Ravens in Swain's ingame particles. Would it be possible to add some Ravens circling around him when he's ulting? Perhaps some Ravens sitting on Terrain, waiting for Swain to proc his passive?
The lack of Ravens is honestly one of my main gripes with his new appearence.
EDIT: HOLD ON, He has random Ravens on the map. I judged too quick.
