Vladamir Crimson Rush
So I just played a game with the new Vlad changes and while I really liked the way the changes to his Q sounded I've actually found out that it's incredibly easy to play against it during the laning phase and difficult to stack up during skirmishes and teamfights.
During laning phase vlad's opponents immediately know when crimson rush is going to proc thanks to the color coded bar under his name, when it starts turning yellow they back off for a couple seconds and come back, at the laning phase this means they have a huge window in which they can bully and harass vlad with relative impunity.
Instead of having such a narrow timing window why not have him work like annie where after he builds up charges he can hold them until he casts next, at which point he would gain the speed boost.
