First of all - just calm down a little.
I am perfectly okay with how the Legion played out and I was enjoying it very much since the launch. Actually since the invansions that came with the pre-patch. The timing and pacing of the coming content was great during most of the expansion. I am fine with the overall design, I love the style, I love the world, I loved the quests, I liked the tiersets. I was not talking about the major part of the content when I was criticizing it. It's the old models, cosmetic items, and more importantly character customization options, which I'd like to see getting updated on more regular basis. Because in fact these aren't that hard to create.
I've created a lot of custom and original content for some other games before and believe me if I am saying we could be getting LOADS of new hairstyles and other features MONTHLY. Even if there was just a small bunch of extra people that would work on this and only this specifically.
The character customization options as they are now are so low effort and so limited that it's almost insulting to the players. And of course I don't want more hairstyles at the expense of better gameplay and quality ingame content. That's why I was suggesting that Blizz should hire some extra people to the art team in the first place...
I hope you do finally get it.
