Why do Skyrim's vampires suck?

I noticed that too. I don't mind the fact that you can't regenerate health in daytime and all that stuff; honestly I was surprised not to be receiving constant sun damage. What did annoy me a bit is that being a vampire only seems to be worth it for stealthy types...I liked the system they had going in Morrowind, where there was a vampire clan for each type of character (the quests were a nice touch, too). My character being a battlemage, the advantages to being a vampire are kind of pointless to him and not enough to balance out the bad stuff.

- High stealth and invisibility means you can go anywhere, anytime without being seen. This makes it easy to deal with stage 4 vampireism.

Not really because invisibility is a power that can only be used once a day.

And for whatever reason, when I try to use the power of invisibility + night eye everyone can still see me, even when I'm quiet and sneaking...

I was talking about the Illusion Spell: Invisibility, not the Vampire Power.
And if you want to do any casting with enemies not seeing you, you need the Quiet Casting perk from the Illusion skilltree.
