Sorry I'm one of the critics it seems. In my opinion, you have some really exciting changes in there but also a lot of things, notably including some of Bethesda original ideas, which are just a bit inconducive to Vampires in general. Really, a Vampire craves blood; needs it, wants it. A Vampire should NOT get more powerful by not drinking blood. It should get weaker. That only makes sense and is possibly the biggest failing on Beth's part; and on yours if you keep it. Then we have general disadvantages/advantages and balance. I'm seeing new Vampire Infamy, Vampire Hunters, unable to use restoration magic, more damaging effect of Sunlight and the keeping of 100% Fire damage. Now look at the good things you're adding: Modified Vampire Drain, Vampire Servant, Embrace of Shadows, and a new Vampire Seduction ability. (3 of which are once a day powers) Unless I'm missing something really obvious all I can see is that you've hiked up the bad things about being a Vampire and then also bashed down some of the good things. But as I said, it's just my opinion, but maybe my comments might make you see another angle to your mod, whether positive or negative.
