Boring? Ya, I'm gonna have to agree there. I would argue that problem extends to his equally boring binary playstyle.

The concept of Flow being a resource bar he actually casted out of seems brilliant to me, but I don't doubt that Riot probably felt that way too at some point. Frankly the nature of his passive as is feels disjointed from the rest of the kit in a very subtle way.
