Jayce-what cant he do?

I know hes not necessarily the best at any role, but he seems like hed be a good champ to master and then play him anywhere. Top-I think here and mid are his strongest roles honestly, no explanation needed. ADC- I remember seeing this a little bit from time to time, short range, but clears well and pokes good, figure with a good engaging support hes fairly strong with his "once engaged jump on in hammer form" jg- this one is kinda dependant on his clears, I could see it working because he has great ganking potential. drop a gate, let a blast go, switch to hammer, jump on and run past, knockback. support- now this one id have to pick my brain for, he has good poke and can strong engage, but id think youd have to change his build up a little bit, tanky at the beginning to get your hammer bash to separate the adc and support, but it seems like it would work.

once again, may not be the best pick, but would he be worth trying to master if only to climb out of bronze-silver-maybe even gold?
