How to nerf Vladimir
Remove Spellvamp from the game (it's such a trash as it only fits well to
and
).
Remove HP-costs on his spells.
Give him an additional passive, which contains that all of his spells grant him a shield, quickly decreasing after 6-7 seconds. This shield should scale with AP. (Maybe 10% of his damage dealt by spells) It should have a maximum of 30% of his max-health.
Maybe increase the heal of his Q a little bit to keep his sustain up OR increase his Q-range.
