On the subject of passives: Heimerdinger

Currently his passive is incredibly underwhelming and pretty boring.

When the initial gameplay update happened 2 years ago, I was really excited to see what riot could cook up. Yet they eventually decided that they couldn't come up with an viable alternative to his current health regen passive. Not only does his current passive not offer any interesting gameplay, its not really noticeable and I even tend to forget its even a passive. I'd rather his current passive be moved to his q and only effect his turrets. The team regen doesn't really fit thematically and is pretty lame way to help for a genius inventor. I think that now rito has the chops to do something cool.

I don't expect much since the Donger is in a relatively good spot right now, just some of that gameplay sharpening riot seems to be fond of at the moment. Maybe something that entices him to leave his illuminati triangle of death. Also just for fun instead of completely killing an unleveled turret when he replaces it with a new turret maybe have him actually upgrade it with his wrench or something if he hovers over it when he q's.
