Has sustain, mixed damage of true, physical and magic, CC and becomes really tanky.

Didn't riot change Irelia for this combo?

-You forget that Cho only has sustain if he kills things, not on-hit lifesteal like Irelia. -Cho is 80% magic damage, 15% true damage, and 5% physical. 'You telling me his autos are doing too much or something?
Irelia also beats Cho in the mobility department, because A ) Trinity Force and B) Cho can't hop to multiple near-dead minions in order to catch up to someone. It's either burn Ghost, Flash, or pray that they're close enough to get hit by a delayed Rupture.
The only way Cho is tankier than other champs is via Feast stacks. Know how to counter that? Kill him. Then kill him again. Then again. Letting Cho stay at 6 stacks all game will let him use it purely on the offensive. Irelia on the other hand keeps her tenacity passive regardless of her KDA.
Not trying to come off as rude, but Cho'Gath is a balanced champion, and has been for some time.
Immobile, you can easily dodge his Q, also they have a large mana cost early. Also he is a tank so do you want him to be squishy? Irelia on the other hand is a better more mobile version of chogath with built in tenacity that makes her impossible to lock down. With Cho at least you can CC him and kill him before he actually does something. Lol
the only thing i find op about cho is that his silence is actually a lot farther than the visual.
im just confused on why his w still hits when i stand so far back and the thing doesn't visually hit me, but it does damage and silences.
