Vladimir is possibly the most oppressive champion in the game.
I mean, pretty much every champion has to manage at least 1 resource. Even energy champions have to be careful in sustained fights, and they can still get poked down in lane, with many of them having little or no innate sustain.
But not Vlad.
He has no resource, which means he can spam those abilities for days His abilities give him ridiculous sustain in lane, for which he pays nothing. It's impossible to poke him down, because you simply can't outlast infinite sustain. If you all in and fail, then he can get back to 100% in no time, whilst you're starved of health and resource.
Who designed this guy?
