I do agree in general, but I can tell you: I personally prefer them making more tiaras and the like!

Although, I do believe that they SHOULD just include adjustments to pieces to accommodate racial features - at least in iconic pieces. Not ear clipping for viera, but something that looks good. It's ridiculous the amount of things that just clip (LIKE TAILS), but potentially aren't giving us longer hair options because of clipping. It's baffling.
I think SE does, and they try to get away with doing less because of it. They seem to be surprised quite often on the occasion the playerbase speaks up about something. Such as with the hrothgar situation.
If they cannot add a toggle, the simple solution is just to cut on the amount of capes. This expansion is literally THE cape expansion.
Yeah, it's unfortunate. I think it hurts every race to just accept lesser quality, regardless of if it's on hrothgar, viera, or au ra and miqo'te. Everyone is in that "similar boat".
As for au ra tail clipping, I generally think it's not as bad as miqo'te, but it's kind of a coin flip. I think it's due to the position of the tail. I'm not sure about that one fatter tail option, as I've never used it.
