- You know how fed a cho gath needs to be to one shot someone with feast?
- Feast doesn't provide CC (unless cho has a Rylais I guess lol)
- You could always kite him, it's not that hard to step off the rupture and walk away
- His cooldowns are kinda long, so if he initially misses rupture and uses his silence he doesn't exactly have much to defend himself
All that said, cho is still a very strong champion.
