Expert take
Vladimir is an excellent champion for players who like turning patience into dominance. He does not only reward mechanics; he mostly rewards tempo understanding. You need to know when lane is already won because you did not lose too many resources, when your W is worth more than a trade, and when Hemoplague should be saved for the real grouped fight instead of a tempting kill. His real strength appears when the team accepts to play around an extended fight and Vladimir enters at the right moment, not when he is forced to be the only engage. Played well, he brings heavy late-game pressure; drafted poorly or played too quickly, he becomes an AP carry without enough room to breathe.
