Can We Please Talk About Vlad
Let be honest this guy is the definition of cancer champion.
Look at his whole concept as a champion and how he works:
Heals Massive Amounts Built In Tankiness Built In Untargatable Manaless
Can list forever but honestly that mean nothing, just think how he actually works:
He divers forward and gets taken down to super low HP then from the press of Q on a 3 second CD he goes back up to half HP, and does this over and over, it's the most BS thing in the game to play against, oh look you got him super low doesn't matter he pressed Q again.
Oh look lets all jump on him, he pressed W and Zhonya's to avoid taking any sort of damage then presses Q and heal again.
This is the single champion that when you thing about it is the worst for being oppressive or broken, cause of what he does.
and
tends to dumpster him. if you don't stand on top of him while he is in w he won't regen as much and with the %of hp cost on 2 of his basic abilities he kind of needs that q heal to do anything without killing himself off
