EDIT: When I wrote this post I wasn't aware of the legion pre-patch coming so early. I've just come back to wow after a couple of years break so guess I had many other distractions from other new content to notice that the patch would go live so soon. Anyways this post is kinda irrelevant now that the patch (suddenly) is live and I can check this stuff out by myself (instead of asking someone on the beta to check it) :)
So now I am considering if I should discontinue my work or continue it.
One thing I've noticed in the youtube videos is that the new bar seems incredible thin (way to thin for my taste!). So I am wondering how much this new blizzard "HUD" can be adjusted? And even more importantly, can it be scaled independently of the rest of the blizzard interface?
