@Riot and Cho'Gath
Think he could get a new passive? An updated passive would breathe a lot of new life into this champion. His current passive is very non-interactive, uninspired, and boring. It does not do a lot to increase a player's sense of impact. It feels like a lack of agency.
I would love to see something else done with this! I'd like to see something that would solidify his identity, such as upon successfully hitting a target with an ability next ability gains (flat number multiplied by bonus health/ap) damage/heal on cast. This would help bring his identity closer to Burst Mage/Juggernaut, which is what a Rioter mentioned might be how he is identified.
On an off note, I saw part of a job application from Riot and this is what spurred this. I wanted to write about this topic, but not apply.
