Let me tell you a story... one of wonder and excitement and fear of the void. I'll take you back several years to when Cho'gath was a common pick.
Cho'gath was sought by teams for his utility, durability, and great burst damage. Picked and banned, top and jungle, he was seen through the rift. On one fateful game by CLG.eu, the kill score was tied at 50 minutes in! A whopping close game at zilch kills per team. Spectators cheered as they cleared wards, hoping for some action before they got bored.
But what could be seen? In the top lane above! A caitlyn was caught, and knocked high above! Cho'gath screamed at the Caitlyn with glee, SILENCE she would be! When all through the rift all the creatures scratched their heads as Caitlyn flashed and netted to safety. Cho'gath's team poorly placed, their summoner's burnt, to get that one catch they had apparently failed. That Caitlyn had been nailed, but a glitch saved her.
Overlapping CC, gave you a frame to react, letting her escape. Teams through the world, stopped with the Cho, and went to other's less prone for this fate. We saw it again, in a game with Yasuo last season. Many people screamed it was the reason for the loss, but Riot simply glossed over the incident as they must for PR.
When a few patches later, they changed their code, got CC lapping to work properly. In the process they broke Riven's Q, and let her auto attack while she jumped too. Now Cho'gath is back, and he wants his fill, beware the void terror for he's out for a kill!
