As someone who tried vlad before the rework and didn't really like him
New vlad seems pretty awesome. The new e is SO MUCH FUN to use. On top of that, i feel really effective once i have some cdr items built.
The ultimate heal is amazing in team fights. Bait master vlad. Drop ult on 3+ people, they dive you while you cast e and q, you pool, then you cast again/hit hourglass and boom full hp.
And since he scales really well with hp now you can get like 4-5k hp and be an actually tankyish fighter mage in the late game.
