Sej "had her time in the spotlight"
I like Sej a lot from a character design perspective. Gameplay however, she feels totally awful to me. She's just a walking (well, riding) ult bot with some of the most comically ignorable damage in the game. Can you honestly give me one reason you would pick Sej over someone like Poppy or even Amumu now?
With the new rework coming up, I was pretty hopeful she'd be pretty good. Then I remembered this quote (title). A real quote from a real human really working a RIOT. Really.
So make no mistake, if new Sej releases sorta strong, the nerf bat will be swift. She can't take precious jungle space away from their long beloved Lee Sin (now with new expensive skin, gib mony pls!).
