I was quickly disabused of that notion when I walked into Whiterun on my newest character at about level 10 and found a Master Vampire waiting for me.
This time wasn't a problem, because there was only him and he was focussed on me, which stopped him from killing off Adrianne and anyone unlucky enough to be nearby, which has happened before.
So, the question part to get out of the way first; If you complete the Dawnguard questline on the side of the Dawnguard, do the vampire attacks stop? If so, I'll simply run through that, being careful with towns until the bloodsvckers are all dead. I know that if you side with the Volkihar the attacks seem to stop, so this is only a 'good guy' (depending on your stance I guess) issue.

Following on from that, I'm certain I'm not the only one who finds the fact that going into towns can now be fatal for NPCs, some of which are quite good characters/have useful functions. Whiterun, especially, actually make no damn sense. It's not exactly lightly guarded. And, while Volkihar seem to have their own lore, if it matters at all then Whiterun has two patches of running water that'd need crossing.
Vampire attacks out in the country I can deal with. That's fine. If they kill me, that's my own damn fault.
It is NOT cool, or even remotely fun (i.e, the entire point of a game) to have NPCs getting killed off with you not able to do anything. I can't be the only one who's fast travelled to Dragons-Reach, walked back through town, and then found a bunch of dead NPCs and some guards still fighting a bunch of vampires and death hounds. It wouldn't even be a problem if the NPCs weren't so damn suicidal! I've had to reload numerous times on my main save because Idolaf and Adrianne kept getting themselves killed. They always, without fail, get themselves killed. I usually find the vampires easy, but the NPCs clearly don't. So WHY are they so hellbent on getting killed?
My request/suggestion, then. Which could also expand to Dragon attacks in villages/outdoors cities;
EITHER:
-Remove Vampire attacks from towns. The fact they can just stroll in and cause havoc isn't believable and, more importantly, not fun. It doesn't 'make you react' or 'make the danger real' like some people seem to claim. When you have to run halfway down the hill to join the fight, NPCs are guarentee'd to get themselves killed. Not a challenge, not 'difficult', not fun.
OR:
-Make NPCs except for guards flee from Vampire attacks (like, you know, real SENSIBLE people would...) and let them hide in houses, etc etc. That way the people who want attacks to carry on are happy, and those of us who are sick of NPCs we quite like getting slaughtered are happy.
So. Just throwing that out there (And getting ready for inevitable flaming...) An answer to the question part would be prime =]
