Let's talk about what you've done to Cho'Gath Riot
Cho gath was a popular champ before you began to rework him...
he had a good kit. And he had around 15% pick rate even before you buffed him like godzilla.
He had a decent kit with its old version of vorpale spikes.
after this you removed them and compensate with buffs on the ult
Everyone was pissed off because it was then too op
Result you nerfed him to the groud
Now he has 4.05% pick rate
GJ RIOT you rework characters which doesn't need it to make them worse and for people not picking them again...
Thank you for killing one of the most popular champion and one of the best kits from league of legends's history.
Reverting all the changes you've done to him before the buff would solve the issue...
