4. Vladimir
Vladimir is going to see a re-work of his Tides of Blood (E). It can now be charged up, and has a slightly shorter range, but can slow enemies when it has been fully charged. It also looks way, way cooler. His Transfusion (Q) has a Crimson Rush component to it, where on the third cast Vladimir gains a slight Movement Speed boost, and the ability deals 100% increased damage while having additional healing based on his missing health.
Vladimir also gained HP scaling on his Tides of Blood (E), and his passive now has a greater incentive for building Health rather than Ability Power. Look for these changes to shift Vlad into a more tank role, emphasizing items like Rylai’s Crystal Sceptre, Spirit Visage, and maybe even Sunfire Cape.
