I just think it is that content isn't all great - I mean past 6 months we've been the testers for a console game (IMO) which means a lot of content has been cut to what could have been a GREAT PC game
Hopefully content will get better but I doubt it will reach it's peak seeing as it has to be in line with console to be the same game (and devs don't overwork)
I doubt it is just Miller having this dull phase
