The current state of Cho'Gath
Let's be straightforward, no one plays Cho anymore. Those few who still did had a couple things very clear "Cho is not a tank but an AP immobile bruiser"
Which leads us to "To consistently land rupture in this meta the target must be silenced and slowed"
The Rylais nerfs were necessary, true, but Rylais was the only thing giving Cho some semblance of relevance. With it nerfed to the ground let's see where Cho is sitting:
42% winrate in the jungle (This is despite being one of the few champions for whom the Raptors and Krug changes were actually good since they trigger his passive several times)
45% winrate in the toplane
48% winrate in the midlane
These are rather sad numbers considering that Cho is played almost exclusively by Cho mains. So what killed Cho? He's had these super low winrates ever since the mastery system was changed. None of them synergize with Cho's kit:
Thunderlords decree is rather weak on him since he only has two ranged abilities, to trigger it he needs to go melee which is: Almost impossible during a gank, not always possible in the midlane, often a terrible idea in the toplane. Despite this it remains as Chos 'main' mastery.
Deathfire is weak because he only has two aoe spells to trigger it with, often used in succession, so no refreshing of the DoT
Stormraiders can be strong if Cho manages to get very ahead on lane since it allows him to chain his combo into an ult rather consistently. If behind however it's a terrible mastery on him.
Courage is awful because rupture is not a consistent spell. Mobility creep is a thing and nowadays anyone can dodge a rupture (at least most meta champions easily can)
Finally Grasp is terrible since he struggles to stick to targets for prolonged trades.
What does Cho need then? He needs some love, fixing the edges and animation of rupture so it actually hits when it's supposed to would be a great place to start. I agree with him having an identity based around hard to hit high impact abilities, so giving him a slightly smaller delay or CD on his rupture in exchange for fixing the W animation so it hits the targets when it should is another good idea. If Cho is designed around people dodging him or dying then I'd rather they be constantly dodging instead of juking once and murdering him during his long cooldowns.
