How do I play Vladimir mid - late game now?

I mean yay, his early game now has more kill pressure than it did before (which is the last thing he needed tbh), but his mid to late game is unless I am playing him wrong, useless. By mid to late game time, 98% of the time the team has an MR item of somesort, making my Q without the steroid buff more of an AA, and his E requires me to chase after them which an enemy team can easily turn and kill me (btw, cc stops E), Idk how I do damage without being focused and having to pop every defensive CD I got.

Before when Vlad was his super sustainable self, I could at least put pressure on carries while being at a safe distance like other current mid laners (LeBlanc, Ahri, Zed, Ziggs, Vel'Koz, basically every other mage). Someone tell me what I am doing wrong or if this really is a problem with new Vlad, cheers.

also if anyone judges me based on how I built him in my previous game, my team didn't have a tank and I thought I could run more tankier with the health ratio on his E.
