First, and I don´t want by any means to come as homophobic, becase there are more heterosexual players than homosexual ones and since most complains about romances in this game have come and still comes from Straight males I would assume there are more heterosexual male players than heterosexual female and homosexual male and female players.
Second, because homosexual players and heterosexual females gets more options and better ones:
_Homosexual male: Gets Dorian (best character of the game and he is considered cute and hot) and Iron Bull (who is more of a comedy romance, his scene is awesome)
_Homosexual female: Gets Sera (fanservice), Josephine (averague)
_Heterosexual female: Gets the best options of the game: Blackwall (the older, strong and caring guy), Cullen (the "hollywood supermodel" romance), Solas (the best romance of the game for reasons I can´t say without giving spoilers)
Homosexual male: Gets Dorian, who some would consider cute and others consider stereotypical and not everyone finds attractive, and Bull, who, according to you, is more of a comedy romance
Homosexual female: Sera, who is almost nonsensical, and Josephine, who I think is a good romance option but she is one of the ones straight males are complaining about so
Heterosexual female has great options (although the two best options are race-gated), but this is partly because simply more of your followers are male. Solas' romance is pretty limited in scope but it is very fun.
Heterosexual male has a cute, girly option -> Josephine and an option that even though some say is manly reads romance novels and talks about love poetry, plus is essential to the plot.
Now that that's done with, back on topic:
Scout Harding needs to be a full romance option. She was so cute.
I do want to see a more masculine gay LI, but most of all I want to see a wide range of options for everyone.
