People should realize already that romances are not bad in itself
Keep in mind you are telling this to a community that highly regards certain games with romance, such as Planescape: Torment and Mask of the Betrayer.
When people criticize Romance they generally do it for two reasons. Either as a generalization of their personal wants and needs or as a criticism of certain studios' priority list. The former is indeed silly and would be reproachable if only it wasn't a standard of discourse in the Internet. Just about everyone presents or has presented themselves as the mouthpiece for a given supposed group (HARDCORE GAMERS want X! The people deserve Y!) and just about everyone who isn't foolish knows to treat their input as the individuals that they are. On the other hand, the latter is a bit more agreeable.
Open the BioWare forums at any time and you'll realize that gameplay and mechanics are of limited concern. Aside from swooping generalizations about the quality of DA:O and DA2 and wether or not one particular poster wants the third game's combat to be more like one or the other, the real priorities of the community lies in setting consumerism.
They are fanchildren of a given commercial fantasy setting, Thedas, and want to consume as much as they can about it, be it in future storylines or little tidbits from the developers. More specifically, the political arrangements of the world are but a sideshow, what BioWare's core fanbase truly wants when they buy games and booklets is to fuck imaginary characters. This is all the more curious because it is hidden behind a facade of interesting storytelling and the image of AWARD WINNING MASTER STORYTELLER® BioWare.
After all, if you live under a rock called Mainstream Gaming and all you know is current AAA productions, you might as well fool yourself that BioWare is the most interesting writer in the industry, when in truth they aren't that good. What sets them apart is that their stories are just much more elaborate than those of most other AAA productions. And what sets them apart, in truth, for the fans, is that there will be a Grand Gamut of fuckable sockpuppets.
Now, to make the argument that this shift of priorities in their storytelling caused a drop in quality for most BioWare games -- after all, the aforementioned facade seems to be a important reason why mainstream media makes so many excuses for Dragon Age 2 and even Mass Effect 3 -- DA2 had a 'great story' in spite of 'a few issues in the weird realms of gameplay' while Mass Effect 3 apparently had an amazingly awesome story all the way to the ending -- to say that growing focus on romances, which comes from a long lineage that runs all the way to Baldur's Gate 1, ruined BioWare games is a much more difficult argument.
Indeed, for all we know the EA buyout was a bit more important than that. Hell, considering their actual repertoire, I'm inclined to say BioWare always sucked and that BG2 was a lucky find. However, what I do say is that when you open a forums you can tell its tone by searching its megathreads. In the Codex the threads are about the whole of games. In the BSN, you will find hundreds of pages for actual romances and thousands more for the proposed romances of the future -- secondary NPCs taken apart and reimagined by the horny minds of fankids. In my mind, this should at least be considered a symptom of the BioWare Decline.
