Cloud Drake Change Suggestion o_O

Hey guys, I feel like the Cloud Drake is kinda weak. What about giving him some kind of the Dead Mans Plate Passive (Of course without the discharge effect at AAs). For example: As long as you are out of combat, you gain Cloud stacks while moving, up to 100. The more stacks you have, the faster you move. Entering combat makes you lose your stacks. At 100 stacks you get +25/50/75 movement speed. This effect would be more useful, as you get rewarded for moving long distances, you can get faster to the lane early, and roam better, but in the late game you can really outplay the other team by being faster. This drake buff could change the way you play the game and it is more of a reward you only get when you adapt to it. What do you guys think about it?
