Jayce is has been overpowered for the last few patches and Riot has done next to nothing to fix it
There is no reason why he should be able to do more than 60% of anyones health from a screen and a half away with nearly no mana costs. It's fucking ridiculous how broken he's been left. He's also impossible to do damage to as a mage because he either deletes you before you get off any spells or soaks up your damage with all these items
.
I'm so glad Breath of the Wild came out so I could entertain myself with a game that isn't this as unbalanced as this game.
