Hey, I love Blackwall and think he's massively hot; I'm sad my character can't romance him, but I will be the first to say that he's not a widely appealing LI. Bull is the same way. Dorian is the a little more widely appealing, looks-wise, though he is very... fabulous lol Which appeals to certain tastes and not others.
Anyway, I don't want to break down the characters. Some I like, some I don't. And it's the exact opposite for the player next to me. It's all down to taste. But that's why I agree with you in that I feel Cullen should've been the least gated male LI... not Bull!!! That is such a bizarre choice. Of course deep down I believe they did it for personality... because they have that very stereotyped belief that a bisexual person will be the most "open" and vice versa. So a free spirit like Bull... of course he's bisexual! And of course he is attracted to any race! *rolls eyes*
Personally I feel the non-gated romances should've been Cassandra and Cullen. Both story-important characters, both attractive ("OMG SHE LOOKS LIKE A MAN" loser comments notwithstanding), both easy, no-drama romances, etc. Then if you want to go down the less traveled path, there are folks like Bull or Blackwall or Solas.
Sorry, didn't mean to put them down. I just exited a game with a Qunari heartbroken for Cullen (who came shortly after a Dwarf heartbroken for Solas), so I'm a little frustrated for her, Qunari players, and Dwarf players.
I get the feeling Bull is very well-liked among the devs, and they assumed he would be more popular than he was. I kept up with all pre-release announcements, interviews, PAX screenings, dev forum comments, etc. I got the distinct impression that Bull and Sera were their favorite companions, as they sang their praises the highest and expressed excitement for players to "meet them," so to speak. When the race selection was announced, Bull was originally going to be race-gated due to animation difficulties, but Epler liked the character so much that he and the animation team worked overtime for weeks to make him available for everyone.
I think the intention for him was to subvert the "Qunari are all stoic and chaste like Sten" stereotype, so they made him hard-drinking and hard-playing and pansexual, but in doing so accidentally fed into the "bisexuals are promiscuous" stereotype. But then, they have another bisexual characters who is not that way to balance him out (Josephine), so... it's hard to find that balance. And to be fair (and I'm a bisexual who hates the "bisexuals are all promiscuous" stereotype too) there's so much more awareness of sexualities of every kind that there are more stereotypes running around, so it's really hard not to fall into at least one, or else limit your characters or create a new stereotype in trying to avoid another. (For example, in the "Unfortunate romance stereotypes/tropes" forum way back, a lot of people pointed out how BioWare seems to keep making more traditionally considered "masculine/aggressive" women like Jack from ME, Morrigan, Aveline, and Cassandra firmly straight to avoid the 'butch lesbian' stereotype, but in doing so create another stereotype; that only traditionally considered 'feminine'/Femme women can like other women, and thus create their own "only lipstick lesbians exist" stereotype.)
However, it also hasn't escaped my notice that the more tight-laced warrior characters are straight (like Alistair, Aveline, Cassandra, Cullen, Blackwall), whereas the more rogueish characters who deviate more from society's norms (like Leliana, Zevran, Isabela, Iron Bull, etc) tend to be more... and that's not okay.
*sigh*
To be honest, I feel like BioWare missed the mark on romances in general this time around. Without putting any characters down (and I'm sorry to offend everyone, I just have strong opinions this morning)... I don't know, they just seemed to go against the way the tide was flowing. I mean, Cassandra has had a very strong lesbian and bi woman base since her first appearance in DA2. She's firmly straight. Cullen has had a large following since DAO. They weren't originally going to make him a romance option, then made him available only to human and elven women. The two romances they added only after they were given more time and given the most restrictions on, Cullen and Solas, wound up rating the highest on romance popularity polls. The only female romance options for men are Andrastian human noblewomen Cassandra and Josephine. If you wanted someone less overtly Andrastian and/or non-human like the dwarven Harding or the elven Sera? Too bad. If you're a dude who likes other dudes, you get the former slave-owner Dorian (though I love Dorian) or the firmly dominant BDSM-pushing Bull. Goody. Want someone more mild? TOO BAD!
I better stop. This is getting way too ranty.
