League of Legends (LoL) Question: Is Jayce viable?

There are a ton of Master and Challenger players that play whatever. Like, actually play whatever. Throughout history, we had a very infamous Challenger player that only played AP Sejuani mid, and nowadays, we have people like Heisendong who reached Masters, maybe even Challenger, don't remember too clearly, literally only playing Heimerdinger in any lane. Yes, a 100% Heimerdinger play rate. Jayce is more than capable of being learnt at a high level as well as being played at an exceptional level. For this example specifically, I know of a Korean player who's currently playing NA called, if I remember correctly, Nakyle, who is an absolutely godlike Jayce. If you're skeptical about Jayce not being rewarding enough for the effort, he will definitely turn you mind around. I'll go look for a video I remember watching of his, I'll be right back...

Alright, I was close, his name is Narakyle, but I was definitely right about him being a godly Jayce player, video here.

As for mid and top, well, if you're going to be dedicating yourself to him, then you'll most certainly want to learn him mid and top. I'd say he definitely performs better mid right now, since he can snowball easier in mid lane due to the champions generally being squishier and hence much easier to burst down. Top lane is a bit passive at times, which doesn't benefit Jayce in the slightest since he needs to spike for the mid game since the general consensus among Jayce players is that he loses impact late game outside of Shock Blast and Acceleration Gate poke on squishier members.

Everything is viable in solo q, especially in normals and as luck would have it, Jayce is actually a solid pick, even in this meta. Also, I believe he's better in mid lane than he is in top lane atm, but you can play him in either lane and do just fine.
