Well, to be fair on this one, it's not like straight gals have had a "Hollywood supermodel" guy in every game. None of the guys in DA 2 fit that trope. Certainly no more so than Josephine or Cassandra do.
I see a lot of people complaining about how the writers are forced to include a variety of sexualities and should just create characters that they want to create. If that's true, then shouldn't the same be said about how they look? They shouldn't be forced to create a Victoria's Secret model looking gal every time, right? They've done it in almost every game, but they decided not to for this one and, instead, gave two perfectly attractive LI's who might be a little unconventional looking.
Cassandra and Josephine are not "perfectly attractive LI's who might be a little unconventional looking", this is not a semantic game, they are ugly, well, Cassandra is plain ugly by most men standards and by videogame standards for female characters sex appeal, and Josephine between ugly and averague.
That said, the right they have to put ugly women as the only romance options for straight men (while actually putting attractive LIs for every other sexual orientation) is the same right we have to rightfully complain about it. And so far there have been tons of complaints about it, not only in this forum, but on almost every major english forum in the internet.
Seriously, I can´t think of a reason for them to do this. I can´t think of a Bioware creative meeting going like:
Bioware/EA worker 1:_Ey guys, we have recieved praise for our straight male catered romances in our games, everyone says they love Leliana, Morrigan, Miranda, Ashley, Liara and Isabella so I have come across a revolutional idea: let´s make ugly women the only romanceable options for straight males in our next game, I´m sure everyone will love it!
Bioware/EA worker 2:_Oh God! Such a revolutionary concept! You Sir are a visionary!
Bioware/EA worker 1:_I know right? And one of them will be a man we will give a female name and tell the player he is a "she".
Bioware/EA worker 3:_But sir, what´s the logic behind that way of thinking? I mean, if we have got praise for our attractive woman being romanceable by straight male players, and we have decided to include in our next game attractive and interesting LIs for straight female players and homosexual males and females, then why would we just include orcs for straight males?
Bioware/EA worker 1:_Ummm...that´s a good question...
(6 months later)
Bioware/EA worker 1:_Well, time is up and we have to speed things up if we want to finish the game so I don´t have more time to think about an answer to your question Bioware/EA worker 3, we are gonna do it simply because I am your superior and I can fire you, does that logic convience you?
Bioware/EA worker 3:_Completely sir, completely.
