Vladimir Counter Counterplay

So I used to main Vlad and as I'm beginning to dabble in him again recently I'm beginning to notice how frustrating it can be to play him. The changes made him very powerful potentially, but it seems as though there is so much counterplay built into his kit, anyone who knows anything about Vlad can easily avoid most of his damage so I'm just gonna throw out a few small changes to see if they could help.

Enable Vlad to cast his Q and R while channeling his E, and then add half of the damage dealt by other spells while channeling to the damage of his E on release. Why would this help? First, it would enable Vlad to be able to deal decent dmg with his E without charging it all the way and his Q without being empowered. it still keeps all of the counterplay built into his kit, but makes him a bit less completely reliant on fully charged Es and empowered Qs, and gives him a bit more playmaking potential, which he sorely lacks.
