Howl in the night instead.

If you just need the regen passive, use Double Bloody Mara drink to keep your vamp at stage 2. So you'll only take 10% extra fire damage instead of 25%, and for difficult fights you can even reduce it to stage 1 (which disables the benefits, but you can easily return to stage 2 by spamming mist form).
And most importantly, you should always try to avoid/mitigate all avoidable damage, even if youre not a vampire. Once you get used to it, the game becomes much easier. If youre a mage, always try to keep your shields up, and dont forget about blade cloak and self-heals if your char is stamina-based. In pvp, vampirism provides some useful tools, such as undeath passive and mist form.

Ill help end your scourge just as I have ended so many others.

Mist Form is just too good for my Templar. Immune to snares (except of course the stupid charge snare) and the only source of Magicka based Major Expedition, and 75% damage reduction is simply too strong for me in PvP.

It has saved my life approximately 14,364 times.

For Sorc I would say no, DK probably, NB maybe yes maybe no, and definitely not for Stamina builds.

Debating if i should drop it.... but Imperial Stamblade needs every bit of recovery it can get.

I never was one to start with.

If you're just using it for regen / sneak, you're just putting yourself at a disadvantage. Being super vulnerable to DKs, meteors, cold fire, and destro ult isn't a fun time.

I would drop vamp only if they nerfed undeath. So many times I expected to be dead but wasn't because of that passive. As a sorc I feel like the extra damage from fire and FG is worth shielding through just for that passive. I also appreciate the extra movement speed if I have to stealth. I'd rather drop vamp in pve, but haven't come across any content that stage 2 can't deal with.

Vamp is insanely good, after a while you forget the fire damage is even there because you automatically compensate for it after you get used to it. Plus there is CP

Extra regen and undeath are absolutely worth it.

Also this thread scared the crap out of me ... I'm planning to take my evil dark elf vampire and when I saw this thread I naturally thought it was getting nerfed again before I can even try it!!!
