I sometimes do. The two 'whines' I dislike the most are:
1) "BG 2 was the greatest RPG ever. BioWare game X sucks because it's not BG 3." - BG 2 might be one of the *biggest* WRPGs, but I've never understood how it constantly made people's top ten lists.
2) "BioWare is doing what BioWare has done for a decade now. I am unhappy with this." - BioWare has a formula. It doesn't make hardcore games. It doesn't do edgy games. It tries to produce the WRPG equivalent of a summer blockbuster. I sometimes feel people who complain about BioWare games would complain that a Micheal Bay movie had too many explosions and a shallow plot. Even when I agree with them (DAO had a hackney 'save the world from mindless hordes of evil' plot) at this point, if you're paying for a BioWare game, you know exactly what to expect.
I guess that some people are still reeling from the fact that BW took a single aspect of their games and made it their main selling point and I do agree with what you said about expectations and BW games.
