There seems to be an awkward dissonance with Jayce's abilities. In aesthetics and actual gameplay.
Now, I KNOW there is no such set rule for what constitutes as magic and what is physical in this game. For example, Ezreal looks like he should be a mage, yet he does mostly physical damage. Nidalee's spears do magic damage. Alistar is nothing but magic damage, etc.
BUT everyone already has an instinct in what should inflict physical and what should inflict magical damage as far as abilities go. For example, if something is purple and "voidy" looking, it's always going to be magic damage no matter what. Take Malz and Vel's kit for instance.
Now to return to Jayce
's kit. I do not know if this has been taken into consideration, or if your champion designers noticed it or not, but the way you distribute damage type in Jayce's kit is downright awkward.
Shockblast(Q) is a pure ball of lightning, yet it does puny to a ton(depends if it's empowered or not) of physical damage. Yet everything players have known about LoL before points that this ability should have been a magic damage ability, even if it scales off just AD, all evidence pointed to it being magic damage. From Kennen's entire kit, to Ryze's abilities, to Blitzcrank's electric abilities, and even Jayce's own W in hammer form points to electricity=magic damage.
(Jinx recently broke this rule with her Zap! as well. She came AFTER Jayce, and I find her Zap! doing physical damage no less weird)
** Thundering Blow (E)** has Jayce swing his hammer really hard. It does magic damage. I guess it's in the same level of awkwardness as Nidalee's Javelins dealing magic damage while her AA does physical. But atleast Nidalee's scales off her AP rather than AD. Thundering Blow is pure AD scaling, has him simply swing his hammer with nothing magical involved, and deal a lot of magic damage. If this ability does magic damage, what makes To the Skies!(Q) inflict physical damage?
I don't know, I guess these two have always made me pause for a second when I look at them. The way his damage types are organized just seems so different from the rest of the champions in LoL. Balance-wise? I'm sure they're all justified. But still, has this thought ever crossed any of the dev's head?
And as a final criticism, this one having actual balance and gameplay impact. His designation as a fighter and how he presents himself points to Jayce being, not Malphite tanky, but kinda beefy nonetheless. Yet it seems like the best way to play him is to concentrate on tons of AD and little to no survivability. I'm not saying he's too squishy to be playable. I'm just saying, the way he is optimally built seems contrary to how he presents himself.
