Buffing Jayce is a huge mistake

Jayce is already pretty reasonably balanced.

A champion design of his nature is exactly where he needs to be and even you kind of make note of it in your patch notes: he's niche. He needs a team built around him to be successful because his independence as a champion is strong, meaning he can do things on his own, but his kit has its potential maximized when he's got a team built around him, not vice versa.

Here's what happens when Jayce becomes slightly better than balanced. He becomes overbearing. And in match ups where he faces the possibility of being killed, he can just farm with his Q and clear waves and not interact. And in top lane especially, he's extremely anti melee, though he isn't super hard to gank - granted after level 7, he becomes very dangerous to gank because his full combo can kill anything short of a armor stacked tank and that's assuming the tank wasn't starved to death by him.

And let's be honest, Jayce is an abuser of FOW skill shots that can't really be outplayed and that's bullshit, too. That's not Jayces fault because riot hasn't addressed that but that doesn't make him less frustrating to fight.

I just get nervous with champions like Jayce. Poke has proven to a very violent balancing point in the past and poke comps can emerge from being bad to oppressive in a heartbeat as we've seen many times before. I also think Jayce is reasonably balance and there isn't any need to buff him. His one downside is he has to rush tear but because he has 6 spells by level 3/4, he's one of the best early game champions there is. Taking away from this is a mistake and could potentially push him far over the edge.

I know it's too late and the buffs are going through but I'm just going to say now, I think this is a big mistake. Not being meta doesn't mean a champion is weak and typically, being a niche pick is the epitome of balanced. There was no reason to change that.
