In light of the recent changes and the fact that Riot is looking at Kassadin right now, i'd like to see two QoL changes for him:
1. Please show the amount of mana he gets back from his W somehow, I have added two suggestions, the first one shows the amount of mana in the tooltip, the other one on the buffbar:
2. If possible, please add the amount of damage Kassadin deals per stack on his ultimate stack counter tooltip, on the buffbar.
