That's just your opinion though.
If you want to be competitive in the high end headphone market, you do sound first, all else is second. If the sound is not right, you are not selling any high end headphones no matter how comfortable your headphones are.
You have to realize that these companies are not selling a lot of headphones compared to some mass produced $100 gaming headsets.
Thus, their revenues are not high enough to dedicate a big budget to both comfort and sound. They prefer to just put everything in sound and hope the headphones are decently comfortable for a majority of people. Moreover, I have heard rumors that Abyss margins are pretty slim as their magnet structure costs a lot to make.
Honestly, that's what I'd like to see - if a headphone sounds superb, I might find ways to make the fit comfortable but if it sounds like a$$ then I won't get it no matter how comfortable they are.
You might feel entitled to comfort when paying $4000 but understand that you are paying for sound first, that's the golden rule.
It's the same way high end motherboards don't have the best BIOS features because motherboard manufacturers don't move a lot of units and instead focus on $100-$200 boards which get regular updates etc because of sheer volume they sell those at.
That said, Diana in my opinion is one of the most comfortable high end headphones for my head. Just go and look at Audeze headphones, ZMF headphones, Raal SR1a etc, none of these are comfortable and yet these are most sold high end headphones there are.
