I haven't watched any tournaments lately, so maybe the pros have been doing this, but I never see anyone play Jayce as an AD carry except me in the games I am in. Why is that? I know he has a relatively low AA range compared to most other AD carries (except Sivir), but he possesses a ridiculous amount of utility, burst, and CC in lane. No other AD comes close. When in Cannon form, your E > Q does an insane amount to the squishy supports and ADs in bot lane. We're talking a quarter of HP or more each time you use the combo and land it, particularly at lvl 5. Not to mention the fact that it has ridiculous range and speed, making it hard to dodge. If you're in a lane with Blitz/Ali and they get their combo off, in combination with Jayce's E > Q, R, Q > E, it's a guaranteed kill almost every time.
And other than his AA range, he doesn't really fall off. He can still do nice poke with E > Q, and he has his W steroid. Albeit his Hammer form isn't as useful late game, but it can be used to clean up team fights very effectively since it gives him all new skills and a little tankiness. Plus you have to factor in the fact that, more than likely, you have denied the **** out of the opposing AD because of his immense lane presence, and probably killed them several times as well, so snowballing is quite easy.
Any thoughts on this?
