Swain's Decripify
So I've been playing this game since just after Yorick was released and have always liked Swain. Have bought all of his skins and am still waiting on Dragonmaster Swain. He can be really fun, even though he is pretty unappreciated and has been for a long time.
Although he lacks cheap lane clear, he's still one of the hardest sustain-mages in the game. I have fond memories of building tanky enough to run into people's faces and scare entire teams into blowing ultimates on me, yet living. After you become a giant and scary bird, Swain generally spends his time sort of like a Singed. This becomes less useful when enemies are able to quickly dash or run out of Decripify's short tether and/or Nevermove's channel. To be honest, I feel like Decripify makes almost no sense for Swain while in bird form and could easily be changed to better work with it.
Simply make Beatrice follow Swain while he's in bird form to remove this problem.
Enemies can still dash or run away from Swain, but then he'd be rewarded more for using his bird form to chase people down and building movement speed to do so. It also shouldn't really change the fun stuff you can do with Decripify now(such as forcing the enemy to run out of the tether while you run away), since you can still do so as human Swain.
