Why do I never see Jayce played?

idk, he's got much better late game now thanks to the buffs.

He requires aiming.

I'm tempted to buy him, but I already saved up for Tahm. :c

I don't think he's that uncommon to see in top lane.

cause hes a lot better at taking half of a squishy's health with E Q.

But right now you're going to be facing at least 3 tanks every game that don't take any damage from your poke. Also you can't play like a little bitch anymore because they'll activate Righteous Glory and ram your ass for being such a little bitch of a champion.

Jayce has become a popular mid lane pick in the LCS.

The LCS is becoming the League of poke. Yet actual mages are being cast aside for AD's who obviously have no mana problems. (or at least no problems stacking Muranamana.)

A normal mage with Luden's already does like the same thing as Jayce QE, and Jayce offers little outside of his poke.
