MY Cass Twinfang Changes from a Cass Main since Release!
Twingfangs should be a filler-Dmg spell while your Q deals the real dmg. Like it was before the rework. Not as hard hitting like atm just more fitting. A Snake is not someone who hurts with bites, but with poison. Still her E should be relevant but WAY MORE toned down.
Her E dmg could be lowerd while reseting the poison on her target and adding 0,5 sec on its timing because, more bites -> more poison in the prey.
So you can stack her poison really with E which makes her E relevant AND still spammable but not her main resource of Dmg BUT it perfectly works together with her Poisons while staying synchd with her identidy of a snake :) This would actually make her amplify effect working :)
Just really tone its dmg down and delete the Sustain changes^^
