When do you plan on nerfing Cho'Gath???

Cho'Gath is simply in the most unhealthy state in conjunction with current itemization. All that champion needs is to buy as many tank items as possible. Tank items are usually priced but his glorious passive allows him to sustain himself, very easily earning minion kill-count and eventually scoring kills, firstly thanks to his capabilities of dealing large amounts of damage with 2 cc abillities and one burst dmg ultimate and secondly due to the ineffectiveness of his opponents to keep up with his sustain, which leads to constant pressure many players succumb to...Unless enemies combine forces to shut him down early match, he becomes a mid-late match "god" locking on certain, high value enemy targets, which is an easy feat, allowing his teammates to clean up the rest of the hopeless enemy team... That's just my opinion though... And I don't have to be an LCS class player to notice flaws, if you catch my meaning....... What do you think btw?
