is only a discution from me and my friends about this build, and i wont to see the advice of other player... is not bad in game, as off tank, and vlad no do so much demenge, heve -100 ap then a normal build, but u heve healt and ress, and i don't heve alternative because is only a example off vlad with diferent buil item, is usless in mid game for me... but in leate game is pritty... is this the difference from a normal build... u must try in game it, and see if is good or not...
the guide is not very good, is my first... i use only a normal code because i don't know other bb coading tx Liv SP for the link! ;) and tx at all for for having answered, i don't thisnk to heve so much answer

You don't explain choices, and have no alternative items/runes/masteries

looks better invite ;)

back to the guide:

best way on seals is flat armor vs ad lane opponent, HP/lvl vs ap lane opponent. IMO 9/21/0 are ok against early game stomper, against other enemies are 9/0/21 or 21/9/0 better.
rework your bb coding, take a look an this guide

Seal of Scaling Health, tank masteries. He doesn't benefit from either of those. On paper it might look like it, but having that lack of armour makes you squishy, even though you might have more health to compensate, and the masteries he doesn't benefit at all. 21/9/0 is better for vlad.

i dont see your problem invite him,the masteries and runes are pretty ok, i onlay swap the ap glyphs for mr glyphs. all runes and masteries are personal prefference, i know that this amsteries/runes work.

u only say "thats wrong,thats wrong" and so on,thats not constructive criticism

Can't say I speak Italian, but I can see flaws in the guide. The runes are wrong, you need more variety in the items section, masteries are wrong, and a bad use of coding. -1
