I personally like at the moment some elements in her development more that what I usually see suggested. Which is to tell the a story about both the living and the undead, not tie her to just the forsaken. Which addresses my main complain.
Overall I try to explain what I think about a selected few things I find interesting in the story, and why. Doesn’t make me an expert or correct, but I think a respectful discussion is a good thing.
Well, I saw descendants of the royalty who ruled the country I live it. Can’t say I trust them one bit 
There are quite a few suggestions. We even briefly touched the “forsaken captive” story that was removed from canon of the game.
I am not sure who you adressing this to. I am one of those who actually sees Calia as a potentially very intersting character. Just needs some tweaking here and there. Admitting importance of both sides is the first step IMO. Turning her from neutral to friendly to the alliance - also a good one. 
True, but I’ve heard some things from the M. Roux interviews that suggests that they are aware of at least some feedback. Hence moving the important story bits from books into the game. And some other comments about handling the character development, etc.
Maybe this “we’re listening the feedback” have a slight effect on this side of the team too. But it’s hard to tell so far.
