So I got him on free roll
What the use of him (3/5 corrode)
Just don't waste fame on Vlad for now, because there are so many better heroes than Vlad now. Rockno is the new Vlad replacement. Vlad's HP used to be relatively high, but now he needs Bulwark as a talent to survive the first couple hits until he procs.
The stun from Vlad used to be extremely helpful, but now that nearly everybody uses Yulephant pet in addition to Blitz scroll, stunning the entire enemy team is more of a hit-or-miss. It was nice to have Vlad in Lava3, stunning enemies around the East Demon for a good clean start.
