But where was it stated that every character, regardless of gender AND race, would have at least two love interests?
David Gaider said it at the GaymerX panel (it's on YouTube, just search "Bioware GaymerX", if you want) and Allan said it on the forums. His quote was posted earlier, I'll look for it or Phate Phoenix might show up randomly before I find it, as she tends to do. lol
What David Gaider said was that they used the chart to make sure everyone got 2 options. He used an example that was basically, "we can't do that because gay male dwarves would be totally screwed", and he said the baseline they set for every group was 2 and that they used "the chart" to keep track.
Allan's forum quote said everyone would get two, but he didn't think it was always the case.
So, it's conflicting information. Was Iron Bull included in the chart because Epler had already made the commitment to fixing him? I don't know.
