Vampires rule over blood, That was the one power that made them one of the most powerful demonic races to exist. However, even this strong ability on the level of a unique skill had drawbacks.
It all depended on the blood that they wanted to control, and their own blood. A vampire's ability to control blood depended wholly on their own blood. Quality controlled quality. A vampire who had consumed the blood of lowly beings could only control beings of a lower level.
While one that had just been born, but feasted upon the blood of a great being could control so, so much more. Blood that had not even left the body of the prey they had their eyes on... A control over your blood that you could not fight against unless you had an overwhelming difference in quality, or supply of energy.
Alan had both, which was why, Victor truly was helpless against Alan... originally.
