Jayce Theorycrafting

Depends on playstyle. Q will be maxed first always because it's good poke and does bonus damage dafter leaving the acceleration gate. It's also his best gap closer.

Probably an early point in all of the skills, just so I can have a full combo and I can have the mana regain on hit. E over W then because the DoT is **** and the only thing that leveling up W does in cannon form is increase how much the speedy attacks do. Unless they apply to hammer form as well, there's little incentive to level the W.

I've been getting all my skills by level 3, but after that, I'm not so sure.

Q is obvious for the poke, like you said. Q also gives a great gap closer and AoE slow/damage.

E is useless in Bow form (to level up I mean). E gives a mega burst in Hammer form.

W is useless in Hammer form (to level up, again). W gives great sustained damage, and once you have Sheen/ Trinity Force + Vampiric Scepter it makes for great "burst" damage and sustain.

Honestly, I think it probably depends on the lane opponent. If it's better for you to be in Bow form most of the time, max W second. If it's better to do a full combo in Hammer/not bad to be in melee form, then max E second.

E in cannon form gives your Q longer range and more damage as well as 2 different ways to make gaps. A speed boost and a knock back as well as giving you a small speed boost if you use both of them in rapid succession.

E increases the range and damage, but it doesn't increase when you rank it up. The only thing that increases is the speed boost.

Max Q, max W, max E!

His q combined with e does some gnarly damage. Overall though he works with standard bruiser stuff and feels very strong. He's also a pretty good jungler with his q doing aoe and his w doing aoe as well.

Try the famous Warmog's Armor + Atma's Impaler combination. It works like Nidalee. :D

the build ive been using on jayce so far goes as follows:

1-2 dorans
mercs/tabi
vamp scepter
BT
triforce
GA
LW
choice item

works pretty well, great dps and not as glass cannony as it looks, especially if you run health/level seals or mr/lvl glyphs. you should be doing one or the other

build i want to try today is going triforce atmogs, to give you a little tankier of a presence in teamfights but definitely less damage. the thing is he scales SO WELL off AD that it's hard to justify building this tanky, but might as well try it.

runes are flat ad marks, health/lvl seals or armor seals, MR glyphs or MR/lvl, MS quints or AD

masteries are 21/9/0, will be trying 9/21/0 today

the big problem ive had so far with jayce in teamfights is that his range is too low to be built glass cannon, but his abilities scale so well off AD that i am tempted to do it anyways. he can deal a ridiculous amount of damage, especially 1v1, and his laning is top notch. capable of getting firstbloods at level 2 with relative ease.

Has anyone got a successful jungle bit yet?

Ok so I figured it out, it's starting with Q that makes it cake. After leash, Cannon Q followed by Hammer Q and you're awesome. I used Rejuv + Pot and had no problems. Properly spec'ed of course.
