Hey GD, I've got a couple questions about how I should be using jayce come teamfight time, after a couple of recent experiences...

What I currently do is before the full fight breaks out I do the accel gate shock blast combo to poke them down as much as I can. Once they dive us or we dive them, I try to get off another EQ then I'll switch to hammer mode and either dive their carry or peel for mine with E. Once I've used my hammer combo, I'll swap back to cannon mode accel gate away slightly, shock blast through it and go hammer mode back in again. Is this "correct"?

I ask because a few games ago I had a team that kept diving without letting me poke some first and then when I would hammer in and run back out to toss another shock blast, the Jax on my team started calling me a "chicken" as if I were leaving the fight.. I told them if I just dove in headfirst right away I'd get destroyed (I entered one of the earlier teamfights this way and was focused down instantly...)

Then last night I took jayce mid (team was fine with that, I asked first since I wasn't AP mid) and the wukong told me I was the tank and should build warmogs first... Since I went mid I started with an early hexdrinker (vs lux) and built damage items. I typically build warmogs on jayce after I have 2 core damage items, the game ended in a loss before I got it though. IMO, with wukong, kahzix, Sona, cait, and jayce (me) on a team, wukong shoulda been the tank (first one in), is that right?

Just for reference my build usually is:
Tear to muramana
Brutalizer to black cleaver
Bloodthirster
Warmogs
Boots (depends)
Misc last item as required

TL;DR how do you "properly" play jayce once teamfights break out? Should I generally build damage items primarily or am I to be a tank? (Again, I'll get a warmogs as my 3rd big item typically, which makes the most sense to me...)

Thanks for the responses.

Bump

u should poke as much as you can until they initiate.always peel for your carry but make sure to used w in ranged form then r to switch forms q to close the gap and hit them with the 3 attacks(from your w in ranged form) and, e to peel and it should do lots of damage. you can go for the enemy carry and blow him up if he is in a REALLY bad position and you can kill him and get away or is low on hp and should not be near anyway.

Sounds like what I'm doing pretty much, Thanks. I do forget to use W in ranged form during teamfights a lot...

Bump for any additional insight? Thanks.

Jayce teamfights are very high risk high reward. Thats why i've started to play glass cannon jayce mid. You just sit back and poke them to death, wait for your team to engage and then ONLY hammer stance for the kill.

Tanky dps jayce just doesn't work anymore

I play Jayce as a second carry, using his hammer form strictly as self-peel in teamfights or to deal some extra burst when the enemy is disengaging. His W is a disgustingly strong steroid on a short cooldown, and even without gate, using Q as an auto reset is very powerful as well. Alternatively, you can jump on the carry as a second initiation and knock them into the middle of the teamfight, which is much riskier and only worth doing if their carry is dealing most of their damage.
