I tried 
once thinking he'd be this awesome ghoul controller and was mighty disappointed when the ghouls just did their own thing. But why is there no summoner champion that had multitasking as a central theme? I know Azir is similar but I mean his soldiers are essentially auto enhancers not actually units you cam use to fight for you.
Well if you like dragons you can train one with this guy 
Yorick is being remade, might end up closer to what you want.
Part of the problem though is the engine the game was build on just doesn't support multi-unit control very well.
DOTA was build on an engine that was primarily around multi-unit control...so I think it had some pet control things that worked fairly well.
League just wasn't designed with it in mind, making it much harder to add and do a good job with it now.
Cause they know people will have a newfound hatred of pokemon.
try theese
Annies rework will put more power into tibbers. Yorick is getting a rework and might end up like that. Heimer, Azir and Zyra already have multiple units to control.
