In my opinion, Jayce has become a sub-par champ.
So first post on the forums, yay, uh, yeah. I'm not good at this, but I hope this is satisfactory and that you can reply with your opinions or correct my mistakes.
Riot's been gradually nerfing him over several patches, which I have no issue with since, yeah, he was a bit OP in some cases. But the way they've been nerfing him has been really... for lack of any better terms on my mind right now, dumb.
A few patches ago, or maybe quite a few, they said that his hammer form wasn't being used enough. So they nerfed his cannon. Understandable, the EQ combo at that time was ridiculous. So playing him became more difficult, okay, good, I'm personally of the belief that if a champion is good, then they should require at least some level of skill.
But then they nerfed him again, and again, and so on. Before this was his cooldown nerf, which already boosted his cooldowns to an iffy amount. 12 seconds just to switch stances? 16-8 seconds for his q? At that time it was okay since he could still chain combos and switch over to another stance. Now the mana costs and stuff are higher, the damage is lower, etc. Pretty much half of every game is spent being OOM.
And yeah, his hammer w passive means that mana regenerates with each hit, but it's just not practical since it restores such a small amount per hit and all of his skills take so much mana that a whole wave is barely equal to a maxed out EQ.
Jayce still does a good amount of damage, but it can only occur once since you pretty much exhaust all your abilities within a few seconds of a team fight and are stuck in one form with 10 second cooldowns for everything, so by the time you can actually alternate between forms in a team fight, it's already too late to do anything. When Jayce was announced, he was portrayed as a versatile champ who could use his cannon combo, switch to hammer, jump in with q, do damage, then switch back to cannon and get everyone out with an acceleration gate, or etc. In shorter terms, a versatile champ that worked well with a team, but could still stand alone.
Now you can EQ, maybe hammer-q in, if you hadn't switched stances recently, w, e, whatever, but then you're stuck with no cannon, no skills up, no mana unless you jumped in with full, and everyone's focusing you since you did the most damage.
The only way I've seen most Jayces participate in team fights recently without instantly dying is EQ, then ditch. So pretty much, just poking and ditching. No freedom to choose a different strategy, no versatility whatsoever.
And his laning phase is atrocious. He can push in bursts, but then he's out of mana and pretty much at the mercy of everything around since, early game, he's too weak to actually do proper damage with autoattacks. Since he's a traditional snowballing champ, he's targeted by most junglers and not only do you have to deal with no sustain whatsoever, even with all mana regen runes, you have to deal with a camping jungler on like every other game. 1v1 is impossible unless you're fed.
I've played league for 2-3 years now, I've played many different champs, but the one I always go back to is Jayce since I always loved the freedom of playing him. Last year, I could carry a game. My typical KDA was 10-15 kills, 2-6 deaths, and several assists on an average winning game. At that time, most people didn't complain about him being OP anymore, or at least in my experience lurking the forums and playing. Now, once again, for lack of any better terms, I can't do shit with him.
I can play most champs at least decently and make a positive contribution to my team. But with Jayce, I can't do that anymore. It's genuinely frustrating to see a champ I used to do so well with and not be able to do anything with it. I've seen many people who used to play him just stop because they can't deal with the limitations anymore.
