Nope no special dialogue with dalish. Had to head cannon my way out of that one with my dalish mage. I just let her have her little running joke, because everyone else there knew it wasn't true as well. I haven't played a human, but mage gets a good number of class options. The racial options for an elf though are really not in good places. Like how there's one accepting the inquisitor position that's like "an elf will lead the inquisition." And some minor changes in how the dalish clan reacts to you, but I would most certainly preferred options regarding things like the fate of the inquisitor's clan and a heartbroken "everything I know is wrong" in the temple of Mythal (accompanied by prompt hugs from Dorian as my inquisitor tries not to cry in front of everyone.)
That is true, the mages did get a good amount, but yeah, it just felt like more could have been done in that regards and really, more could have been done with the origins in general, I think that was the main thing that disappointed me, besides the final boss battle. I picked Trevelyan Mage because that was the origin that interest me the most (a mage involved with the negotiations at the Conclave and possibly the rebellion, that was going to be great), but then it never really went anywhere beyond a few dialogue options and dealing with lower approval at the Ball.
It is definitely unfortunate that the Dalish didn't get more since they are so connected to the game, especially in the later part of it. It feels a bit like a missed opportunity (And yes, there definitely needed to be more hug Dorian options, throughout the game)
