Vampire Sorcerers still good?

Nocturne Saint

I had made a sorcerer a while back and had a friend infect me cause I heard they were good. Came back to him after a long time and hes level 10. Are they still good for pve? or should i get cured so i don't have to feed to get rid of the extra fire damage, and atm I'm against an enemy that uses nothing but fire damage, and can't seem to find a single lone npc to feed, in fact I don't know how to feed on pc what key to press after I go stealth near an enemy xD

Yes magicka sorc is super strong in dpsing, and it is nice to have vampire for the increased magicka recovery as well the damage reduction when at low health, and really the increased fire damage is laughable.
To feed you need to stealth behind enemy, then an option will prompt you to press X to feed.
