However, Jayce's poke is not truly determined by the cooldown of shock blast so much as the cooldown of acceleration gate if you want that high DPS, and his hammer stance is less effective against squishier champions.

You took into account the Renekton's runes, but not the Sona's? Not much else to say about that one.

And Tankerdinger does the same thing Heimerdinger does, his turrets have fairly high base damage, so he can still push effectively once you get to level 5 turrets for the aoe, the reason Tankerdinger works is because it punishes stupidity EVEN MORE than AP Heimerdinger, because he can kite around turrets for even longer, while their strong base damage will tear people apart if they stay too close.
