BioWare hasn't even written a proper romance yet, and you want to throw in more variables, gomez? Besides, they've been down this route before.
So why are you playing Bioware games if you don't like the way they write romances? Considering its a large portion of their game(s) dynamic to include such an option and you're sort of missing out on a large portion of the game play by not doing romances.
You're skipping out on a massive portion of character development if you don't at least tread a bit into the romantic side of the pool. Without those particular elements involved their games would feel rather lack luster. If you wanted better RPGs they have those, if you wanted better combat there are games that have that covered. Very few games that don't deal strictly in romance have bumps, and there are very few games you'll find that even get it close to right.
Based on you saying someone else's tastes are gross I'd put you in the category of loving Rom-Coms as one of your favorite movie types because by the end if a Rom-Com its all wrapped up in a neat little bow. Bioware gets to touch on the weird stuff that actually gets a romance to work (as well as what happens after the credits roll since they have sequels) which most companies wouldn't even attempt, I think they could do it at least decently if they tried.
As for romances they've already written, I really enjoyed Leliana's story with the Warden as well as Morrigan's. Neither of which pan out quite the way you want them to, consider Morrigan departs no matter how you handle her (and ends up pining for the Warden later) and Leliana ends up in the Inquisition because the Warden leaves to be the Hero and find a way to sever the Calling (If your Warden is alive).
They also do tragic love rather well in many sections, such as Hawke and Anders in which you may have to kill the character you've romanced yourself to because of his actions.
