I've got an idea for an extremely balanced champ its SO LEGIT that it's 2legit2QUIT.
Edited: First off watch this while you think about this champ: https://www.youtube.com/watch?v=BHtSwocAfJU
I say we make a champ with FOUR (4) gap closers and make 3 of them do damage and one knockback, and one of them make a huge high hp shield. Let's add an aoe stun and high dmg. Let's also add a power-up AD buff ultimate that has an insane high damage long-range execute. Let's make the character have NO resource cost and have super low cooldowns and basically be able to solo a team with 2 items. Seems totally fair and legit.
Oh wait... damn that sounds like Riven.
