Riot Balancing Logic
Morgana: Gets played varily often: Dark Binding: 11 seconds cooldown; 50-90 mana cost; 1175 units range; broken hitbox; 80-300(+90%AP) magic damage; 2-3 seconds snare
Varus: Currently low played: Chain of Corruption (his ultimate): 110-70 seconds cooldown; 100 mana cost; 1075 units range; 150-350(+100%AP) magic damage; 2 seconds snare
Just want to bring up how a basic spell out shines another champion's ULTIMATE; and you cannot really say it is because Morgana doesn't get played, because she does. Now champions that get played that need nerfs more would be the likes of Zed, Leblanc, Annie, Kararina, etc. The point being a basic spell should not be stronger than someone else ultimate, or even close to being on an ultimate level spell.
