As for the other legendaries you have; because none of them are particularly great for you (aside from the shoulders, but you don't really have the other pieces needed to make them spectacular yet), you might want to start looking at them as stat sticks for now.
Take off each legendary and, in its place, equip the best item you have for that slot. Your best non-legendary belt, chest, rings, and shoulders. Now, and I'm assuming you use pawn with accurate simcraft weights or are capable of determining upgrade value on your own/some other way (hint: use simcraft weights in pawn), check which legendary items grant the largest improvement. If equipping the bracers is only a 7% upgrade because you've got a great non-legendary pair, but your chest is a 35% upgrade because your non-legendary version is garbage, you should probably start wearing the chest instead of the bracers regardless of the legendary affix. Do this and determine what your best two legendaries are stat-wise, based on both their stat allocations and the level of upgrade between them and your non-legendary alternatives.
Once you do this, you can then pick-and-choose which to wear if you have any that are close in value. If, for example, the chest is your best upgrade from non-leg to legendary in that slot but afterwards the other options are relatively the same in upgrade value (I'd say within 5% or so of eachother, tops) you can then select one based on personal preference. If you still want to min/max your options, the Sephuz ring has a ton of crit on it (something you could use!) and is the only legendary you have that can actually contribute a reliable DPS increase without needing to change your spec or wait to loot other pieces for it to be at full potential.
I know you're already using the ring, and chances are it will be one of your two best even after you do what I've said, but for all I know you've got a decent non-legendary ring to replace it with but you've got other slots with terrible alternatives. If this is the case, it may be worth using a legendary with a worse effect for the better stats, assuming the gain is large enough.
I'm rambling; tl;dr version: Treat your legendaries as if they have no special abilities on them and are just stat sticks, and determine which of them gives you the best stats compared to their non-legendary alternatives, the gear you'd wear in their slots if you never had that legendary to begin with. Base your choices on that before basing it on what the legendary actually does.
If everything were absolutely equal stat-wise, if you were equipping the legendaries solely based on their special affix, I'd probably stick with bracers/ring myself. The ring can still contribute DPS on a kick/stun, and while without Bloodlet they're nothing special, technically the bracers are still contributing damage any time there's more than one target around.
Use a bonus roll every week trying to get the CoF trinket from the second-to-last boss in Nighthold. If you can do that, and possibly also get a relic that reduces your Meta cooldown, you'll be well on your way to gaining the two-minute meta CD. That'll be a lot of fun for you in raids. Getting the shoulders is the hardest part for everyone; as unlucky as you may feel with your legendaries, you've completed the hardest part of earning that 2 minute meta cooldown. Aside from hoping for new/better legendaries, if I were you my goal would be getting that CoF trinket and 2-minute Meta. You've done the hard part already; get the trinket at all costs. Kill Elisande on as many difficulties as you can each week for more chances on it. Once you can fight her in LFR, farm for it in there too; the lower item level may mean less agility on the item, but the cooldown reduction should remain the same. Kill her on as many difficulties and use as many bonus rolls on her as you can. Once you get that trinket (and, again, potentially one of the meta CD reduction relics) the game's going to change for you pretty dramatically.
Sorry for the spam. Hell, halfway through I gave you a tl;dr breakdown and then continued on spammin'! That's what happens when you're an ADHD poster boy and are on the forums at 5am D:
