On the majority human female elven companion, I've mentioned this in another thread, but here it is again.
Of DAO's 10 potential companions with DLC, 4 were female. 1 golem and 3 humans. Of them, the 2 youngest humans were romance-able. (Though I can't blame this last one). And Male Human Nobles had the extra option of marrying the human queen Anora. This, compared to 4 non-human male companions (a dog, dwarf, elf, and Qunari) and 2 human companions. Of them, one human and one elf were romanceable.
DAA brought us 2 female companions, neither surprisingly human. 1 dwarf, one elf. Neither romanceable (nor anyone in that game.) Contrast 1 dwarf, 1 Fade Spirit (Justice) in human corpse, and 2 humans.
Of DA2's 10 potential companions with DLC, 5 are female. 2 elves, 3 humans. Of them, one human and one elf is romance-able. Of 5 male companions, we have 1 dwarf, 1 elf, and 3 humans. Of them, 2 human and 1 elf romance-able. I guess DA2 is more even than most.
Of DAI's 9 potential companions that we know of, 3 are female. 1 elven and 2 human. Of them, we know of a romance-able human and one elf. This, compared to 4 potential male non-human (a dwarf, elf, Qunari, and... spirit?) and 2 human companions. However, when you factor in advisers, we also have two female humans: Josephine and Leliana. For prominent NPC's, we have Empress Celene and Morrigan. Guess what? Both human! I know it's important to the story and their characters to all be human, but... it seems to be that way with most female companions and prominent female characters in these games, doesn't it?
In fact, looking at the Inquisitor with companions and advisers around the table, I spot 1 non-human woman: Sera. In contrast, I see 4 non-human males in the room.

And again, of all the female companions across all the games, we've had two non-elven and non-human companions: Sigrun and Shale. None of whom were romance-able. This, contrasted with the much higher number of non-elven or human male companions. DAO and DA2's Dog, 2 Dwarf (Oghren and Varric), 2 Qunari (Sten and Iron Bull), 2 Fade Spirits (Justice and Cole). While Iron Bull will be the first non-elven/human male romance option, that's still one more than women.
Would it really ruin BioWare, or kill suspension of disbelief, to write more female characters that don't fall into the human/elf binary? And, while they're at it, consider how not just human and elven women are desirable as romance options, while the characters are being written?
That's how I see it.
