Really nice guide imo, thought me so new things

Im good with vlad, but far from pro, so will take learning from your guide

Anyway I use to have these masteries:
http://leaguecraft.com/masteries/1003400100000000000000000000033140102030301Never tried the ones you have, maybe they work even better, idk

Imo vlad is weak the firts levels, but lvl 6-7 he is strong, until endgame, very late endgame he maybe isnt that super good, then its carrys time to shine! ^^
Vlad is gay though! =P
My m8 always tell me to max W first, its has really nice dmg then and low cd, but I as you like maxing E first, works good imo! :]
PS: And the maths are good for people who have thought about it themself (me), and people who havent played him.
