Also doesn't help that a lot of fun mechanics are hidden behind legendaries, some of them being new ones but also quite a few of them being old class mechanics stripped from the class such as the warrior's execute proc, so not having certain legendaries can simply make a class a lot less enjoyable to play. It's kind of similar to tier sets but those you can always get if you put in the effort, with bad luck it may take longer but at least you know exactly where you have a chance of getting it every week, with legendaries you have absolutely no idea what you will get or when you will get it.
It may seem silly to casual players but I have had several raiders in my guild burn themselves out farming mythic+ only to reach 5 legendaries without getting the ones they want and just quit raiding as it's almost impossible to reach 6+ legendaries without extreme luck due to the soft cap. It's really just such a fucked up system and It's definitely the worst part of legion by far. Doesn't help that it feels like how much effort you put in doesn't reward you at all. In our guild our 3 main mages don't have bracers but an alt and a social does.
Also about the shadowpriest thing, they can definitely be a huge boost as they can often be the difference between making it to the third void torrent or not as they make it a lot more forgiving, especially after the nerf. Also with next patch the belt only gets better with the increased insanity on mind blast and more focus on other playstyles than stm.
