The problem is that after DG, she tends to bland out...
However, I do agree that those ice spikes are a pain...particularly when you are just about to put the love bite on some staggering around soul and she wallops them out with a chilly spear.
I just had a cracker of a laugh though...I was riding up to whiterun and see a dead rabbit, next thing, a wolf leaps out, followed by a bunch of bandits...by the time I dismounted, Serana was knife-fighting the wolf, and Serana's rabbit thrall was bravely battling the bandit horde.
The most irritating thing about her to me is that crackling bacon sound when she's out in the sun...her yabbering is one thing, but the frying bacon is just annoying.
Bacon!?! That's her skin?

I thought that was the sound effect for her shock spell looping. I hope that's what it is at least...
I've also had this issue with Serana stealing my kills, lol. Took me forever to perk up my VL form, I finally stopped casting the life drain spell and when to neck biting. I had more luck with that, but still
