TES has never been a series where you are FORCED to do anything, if you require the game to FORCE you to do things...then you are seriously playing the wrong game...
I never said " forced ", the attacks are supposed to be " blinders " to focus you on the quest, not force you. You can go about what ever you want, but then you run the risk of an attack.
I went to winterhold, there was a vampire attack. I took care of them with no problem, as I finish a dragon attacks. I take care of it no problem. I would be fine at this point. But, then I hit the wait button, wait 3 hours for npcs doors to unlock, and there are vampire in front of me. This kind of stuff should not happen. It'll be like if an another dragon attacked after waiting or exiting a house, right after another one had. Which doesn't happen.
I'm not asking to nerf the vampires. But, in some games something is wrong with how much they spawn. And enough people had said they don't lessen after the MQ is done.
It needs a tweak. You're lucky, they lessened for you. But, like other issues, it doesn't happen in all games.
Ok well if it's a spawn issue then I see where your coming from. But I really wouldn't hold my breath if I where you guys, from my understanding it's a bit of a pain to patch DLC so there's a chance that Beth. won't send out any patches for Dawnguard.
