Yep. I think people need to think about it more broadly. Look at Mass Effect. Look at how being human and overcoming the odds was such a crucial element of the trilogy. That wouldn't have been possible had Shepard had the choice of being a hanar or an elcor. BioWare would have had to dilute the experience being Shepard is a "Spectre" and that would have been the extent of the character development. It's just not as compelling.
I understand the want for there to be more races, but you just end up hurting the story and hurting character development in general. You can't have your cake and eat it too. It's just not financially feasible nor practical.
You "overcome the odds" in every Bioware game, ever. Humanity overcoming the odds has only been done about a hundred billion times, and I'm probably missing a few. Practically every sci-fi ever has humanity as the odd man out, doing something incredible that nobody else can. Humanity is basically the John Cena of the fantastical storytelling medium.
It sure as hell didn't stop Bioware from dropping a million damned balls in the course of the trilogy. The human-dominated Council from ME1's renegade ending? Retcon beamed so hard it wasn't even a thing. You didn't even get to see the Council's holograms in ME2. The waffling on the Spectre status in ME2 applies to literally nothing - if Anderson is the councilor you get it back, and nothing happens. If Udina is the councilor you don't get it back, but nothing happens because Bioware gives it back to you at the start of 3 anyway. Then there's the councilor choice itself, which also gets flipped if you picked Anderson.
It isn't "humans make better stories!" it's lazy damned writing.
My human Warden had no stake whatsoever on the choice of Dwarven King in DAO, he just needed something done. Either of my dwarves, however, really did - do I pick the one that's stood by my family all along, but might be a worse candidate for Ozammar's future? Do I pick the other, regardless of my background? What about my character's family? They're decidedly better off with Bhelen if I'm casteless. The City and Dalish elves also had connections to plot stuff, and even the Human Noble does - even if a lot of that plot is dropped.
Here's the kicker: Inquisition does a lousy job at this. You get choices, but they're rarely personal. Your companions aren't your friends as much as they're your employees, and it feels like it. The Inquisitor himself has nothing relating to his background outside of some war table missions. You never get to meet any of your Qunari mercenaries, or your Dwarf Carta family members, or the Noble's family or Dalish clan. DA2's story was done badly, but it did have some resonance because Hawke was connected to a lot of it - the entirety of Legacy, especially if you have Carver or Bethany around. It wasn't because he was human, but because he was connected to the events in a personal fashion.
The Inquisitor is just kinda..there. You show up, get a glowy mark on your hand, and proceed to walk into the leadership of the Inquisition without a damned thing in your path. The Wardens all had to overcome something before they got there, even Hawke did. DAI's just a power fantasy without any of the real elements that make that sort of thing endearing.
