I feel like 4 spells is not enough to balance some champions

Mostly talking about assasins. Giving them more spells to cast and reducing power on existing versions can lead to helthier gameplay i believe. Currently assasins are more like one-trick ponies: If zed lands his Q, he kills. If not, he escapes. If fizz ults you, you are probably dead. If not, he will just wait for cd (assuming he is not fed yet). Making assasination combos not relying on landing one single spell and making them more comboey can both increace counterplay and reduce frustration. Yes assasins will require more skill to play, but i think this is reasonable if you can kill target for free and get away with it.
