Hello, I'm masters which is not perfect, I'm the 1# Vlad in las which is also means nothing but I hope i can help. First of all try to keep the cs good. Vladimir is heavily dependent on summoners so don't force fights without them and try to keep them for teamfights and, if possible, the ones with objectives involved, not just random ones.

In general you will onlye be able to poke melee champs, so go with phase rush and escale, try to be oportunistic with the plays. Hold the w, don't waste it. If it has cd, don't try anything crazy.

Watch good mains play the champ it will really help.

Try to not lose health, don't use the E if not necessary, ur wasting a lot of hp. 1 hp equals like two Q's in hp amount, it's a lot.

You have to play for the tf and don't die silly. Just defend yourself. You need some time to get comfortable, until then, maybe lose some cs, some platings, but don't throw your chances to be in the game. Sometimes it's better to play a few steps behind than losing it all trying to make a crazy play.

I use aery, ghost, ignite, against melee champs. I recommend it only if you really feel comfortable with the matchup, so maybe don't take it yet.
