“Submit to the hammer. His E in hammer form is basically a better Singed E and his damage is bonkers. He has all the hard to fight qualities of an AD bruiser whilst also having the hard qualities of an AD ranged. You likely won't win this lane and that's alright. Jayce falls off if you keep him in lane, just weather the storm.”
“Recommended: Standard Runes & Teleport
Tips: Your W blocks his R-enhanced AA and his CannonW-AAs. Passive shield his Q and AA poke. Engage when he transform from Hammer to Cannon, because then he doesn't have access to Knockback-E during the trade.”
“One of the tougher matchups for Jax. He will poke you a lot and if you engage on him he will melee form E you away. Build Steelcaps and try to bait his E. The best moment to engage on him is when he swaps back to cannon form as then he cant knock you away. Jayce's are usually pretty squishy so if he gets caught he should be relatively easy to kill.”
“Probably won't see him until you get to higher levels because low elo can't play Jayce for this lives. You get a bit of an edge post 6 but staying even for that long is a challenge. Pick a sustain start because Jayce has early mana problems and it will cost him mana to poke you outside of auto attacks which don't do much damage early. Keep minions between you and him so he cannot poke with Q. From my experience, you do outscale this guy if you make it out of laning phase because he doesn't build many defensive stats and is mostly lethality. It will usually require catching him by surprise though because his Hammer form E knocks you away and his Cannon form E gives him moves speed.”
“Jayce is pretty hard early game but the longer the game goes the easier this matchup gets, and since Urgot is ranged with a pretty safe kit (having an escape + shield) you should be able to survive, try not to trade with him very much early game and dodge his Q's the best you can. once you have Black cleaver + ninja tabis you should be able to win 1v1, you can also go Q max in this matchup if you're wanting to play more safe and just looking to poke him out of lane since you shouldn't be all inning or trading much early game.”
“Jayce has been one of the hardest counters, for quite a long time. He has range, gap close, CC, mobility and better wave control and better burst. Avoid getting into an extended fight with Jayce, keep your distance and use minions to body block his (E) > (Q) range combo. Never let him get behind you, he will CC into lane cutting off your only route for escape. Maxing your (Q) can help with poking him from a distance as you want to not get too close. Also be aware that good Jayce players will (Q) > (E) in fast succession making it really hard to dodge his combo. He tends to fall off in comparison to our burst unless he purchases Maw of Malmortious.
“TL;DR - SKILL MATCHUP IN HIS FAVOR. DODGE HIS POKE. RUSH STEELCAPS. CONQUEROR IS BETTER FOR CLOSER FIGHTS/IF THE JAYCE IS GOOD. DONT FIGHT BEFORE LEVEL 3. TRY TO FIGHT AT LEVEL 6.
Jayce is not too strong in the meta at the moment but a great Jayce player can make him work anyway. Read the Ranged Matchup Playstyle I have written below for a good idea on how to play against all ranged champions. With Jayce, it is recommended to go for an early Steelcaps rush as that will completely gut him. Most Jayce players opt to go for Lethality early on in order to snowball too which would be negated by Tabis. Against Jayce, Conqueror is a must as you won't be building damage early.
Try to dodge his skillshot poke early on and get used to it. It does a LOT of damage, even if the Jayce is inting. Being poked down like that can lead to him just killing you in a single combo which is sometimes just sad as you watch yourself try to crawl to him and he knocks you back and puts you down with autos. His form change has a cooldown so you can try to play around him not having access to his melee form if possible.
The most important thing when fighting a Jayce is positioning. He is a VERY good trader and E->AA->W->Q Combo is just not going to cut it as he will just dash to you, knock you away, go ranged form, auto you 3 times and then fire his blast at you. And at a closer range like that you will not be able to dodge it which will just lead to you getting pushed out of lane. What you have to do is to just all in him every chance you get. Just drag the fight out. What you have to do is E and then just walk behind him or walk between him and a wall. It is no problem if he knocks you back before you can. Just try to make sure that you E or W him. Darius’ abilites are unstoppable so even if Jayce knocks you back, the slow/pull will still lock him in place which gives you time to catch up to him with ghost. If the E WORKS however, don’t use AA or anything. Just walk behind him and THEN do you combo. He will either A, Flash+knock you back for a disengage or B, knock you back behind him and start kiting you. Ghost will help you catch him at this point. You will probably be able to catch up to him regardless and kill him anyway. A Steelcaps rush helps in a situation like this as it prevents him from killing you before you catch him. If you need even more tankiness, buying and sitting on a Chain Vest is great.
A Jayce matchup is somewhat oppressive early on but he really should stand no chance after level 6. Just try not to die to him.”
“Jayce is a big lane bully and will punish you if you let him. Either parry his knock back or when he jumps on you. A lot of Jayce players hold their knockbacks which can be tricky. You mainly want to farm this lane so take corrupting potions or Dorans shield and wait the lane out. You outscale him.”
“This lane is really easy if you can survive until lvl 6.
If he has Phase rush, avoid all-ins and keep poking.
Olaf is better in teamfights.”
“A good Jayce is hard to deal with as Sion but most Jayce players are not good enough to abuse you. In most situations you can just slow him with your E and Q him when he tries to go up and poke you. If he jumps on you with hammer form he will try to cancel your Q with he hammer form E. This is fine as it puts your Q on a 2 second cooldown and if you can catch up to him you should be able to win the trade.”
