One thing that worries me...

I think that this could be a great add-on. I just saw one thing in the trailer that worries me. Skeever infestations and giant attacks seem like they could certainly be interesting, I just hope that they will be well-balanced. Dragon attacks (or the Dawnguard vampire attacks) that take out half of a city's population and force me to re-load just so I can buy some smithing supplies without being hastled is a bit annoying. Will giant attacks or skeevers be a similar nuisance? Am I going to have a basement full of skeever bodies after a weeks worth of gametime?
