PvP legendary

I’m looking for advice. I plan on doing 3s and RBGs and just got this character to 60.
From what I’ve been reading on WoWhead and observing others, most people like to go for the Chaos Theory legendary. Should I craft it for the Waist or the Gloves?
Are there other legendaries to consider?

CT is good for teams that don’t have a lot of CC and you want pump. My preference into teams with a lot of CC I like CA, the heal is good and does decent damage.

how do I know which gear slot to use? (like gloves or waist, etc)

I think mvq uses cloak for CA. For CT I went gloves cause there isn’t any haste/vers gloves from vendor. And CA I have wrist

yea, but I see some people go with Waist still for CT
I just never know how to decide these things on my own
I figured waist for CT made sense because aren’t gloves apart of a tier set, which is going to be a thing next patch? IDK

And thank you for the CA advice. Just got my CT today from LFR CN luckily
