Vladimir

Honestly, he likely benefited in some regard in terms of the nerfs to mana regen items in Season 5.

What makes you think Vlad isn't good now?

Vlad is a strong pick against Zed and many other champs.

He has a place, and I for one don't want to see him any stronger. His late game AoE damage is insane.

Someone mentioned a QoL buff that might break him or make him played more.... For his troll pool to go through places you could dash through with other champions. I didn't agree with it, but maybe a step in the same direction of a small buff that would increase his pick rate and perceived viability.
