I don't recall jayce having any nerfs, his e,q combo still makes insane dmg, and i don't see a reason why he isn't being picked, also he is a good champion in top lane for a potential and very common laneswap...
Namnoms1 votes2 ADC meta already in, no room for more AD in comp
Oddysseas1 votesWell we see alot of ap going mid with xerath, lissandra, lb, even victor. The junglers are usually building tanks like jarvan, rek'sai so i don't see many duo ADCs.
Renaille1 votesbecause he can't bully out melees when every top laner in lcs is a ranged champion(except irelia)
Oddysseas1 votesJayce can't bully??? I think he can, plus mao kai isn't ranged, rumble not ranged eithe, and gnar i think he can be bullied by a jayce if he can place a q,e combo while he is in mini form.
It's that the laneswaps are very frequent and i thonk jayce could handle a laneswap easy
RazorTS1 votesnot tanky, slow build up path, other top/mid laners provide more for the team
Only Play Darius1 votesBecause he got nerfed to hell.
Oddysseas1 votesDid he? I don't recall it. How ?
Only Play Darius1 votesI think that he might have just been outdone by 
.
And the mana regen nerfs couldn't have been good for him.
Hasztalan21 votesHe got hit by the nerf bat with the W change. Look it up in the patch notes. It was literally which killed his lategame.
