There seem to be a lot of people here who forget that almost every criticised aspect of Oblivion was put in the game in response to complaints about Morrowind. It sometime seems to me that if Bethesda want to make the best game possible they should start by ignoring everything the fans say.
Hardly, most aspects criticised were found in Morrowind and remained unchanged despite many complaints, like the levelling system. Oblivion felt like it hadn't been play tested. Bethesda just ignore any real feedback in favour of gimmicks like dual wielding.
