Why is Vladimir so popular?

That's so false. I see Vlad's getting stupid fed all the time and carrying hard. His early damage is low but he is by no means weak in the early game. He is ungankable, unkillable and has outplay potential that rival's Yasuo himself. If you ever face a good Vlad one-trick, I swear you'd never want to play this game again.

Get an Executioner's Calling. It's amazing how 800g can just destroy a champion.
