Vladimir is currently struggling; he's primarily played in the top lane over mid, and many players believe he needs buffs to be relevant.
His laning phase is inconsistent and no longer considered exceptionally strong, with his once-dominant late-game carry potential also seen as diminished.
Be extremely wary of anti-heal items, as they severely counter his sustain, and prepare for difficult matchups against specific champions like Yorick, Orianna, or Akali.
