Daily reminder Cho's W needs instant cast
Against an opponent with 2 ways of avoiding damage cho gath basically only has a bit of on hit damage and his ult. If you react well or have good movespeed you can dodge q anyway. Reducing the cooldown on the w isn't really compensation for losing instant cast(hence the winrate drop). In all ins it is easy to dodge because it is such a delayed attack. They didnt change the mana cost either, Cho has a big mana cost on his w, now it will do nothing much of the time. Instead of making w instant cast they could atleast reduce the cast time.
