I think I've drawn a correlation on my game; the day after I bought a cow, I had a giant attack. It killed the cow and I decided to not buy another one. I then went AGES without another attack of any kind (well, I did get one skeever infestation I suppose, but thats so minor its not worth moaning about). Then I eventually adopted a son and made my way back to the house to find a bandit attack. Nothing since then. I think some people are just getting a DG style vamp attack bug, if the devs had wanted attacks 'every 5 minutes' then we'd ALL be getting them. Mine seem tied to house upgrades and have been very few and far between.
On top pf the fact that these are not the EXPANSIONS we were promised. Just more Horse Armor sized junk DLCs IMHO. Slowly Elder Scrolls is dying out in my heart and not worth playing anymore. Sad because when I fell in love with the series, I thought it was going to go on for along time. Not have it torn apart at the hands of incompetent Devs.
DG and HF are in no way comparable to horse armour, IMO thats a ridiculous comparison. Also, we were never promised expansions. The only thing said that included the word 'expansion' was that we would get 'DLCS that
FELT LIKE expansions.' Two very important words there. More to the point, if they are making an expansion thats going to be the big feature DLC for this game, they wouldn't release it remotely this early, it will be kept very much under wraps, and they wouldn't want it tied into the MS deal. That particular DLC release must have zero hiccups, even if it means keeping EVERYONE in the dark. Thats my uneducated take on the matter anyways.
