I do. I have 4 pieces, but never got the helm after 2x exalted Sha’tar, so had to make do with the helm from gruul’s lair 
but have every other piece. I wear my sha’tar tabard proudly lol.
Been wanting the helm myself so I can put on my Demon Stalker w/o breaking the 4 pc bonus (and meta). But if a hunter is in my mech group with my hunter, so be it.
I’ve lost the hourglass 5 times, one day RNG will work out for me (hourglass or abacus) without my being an ash-hat and exclude melee dps and hunters from my BM/mech groups…
Dime a dozen dps is not really in a superior position to pick his DPS. Hope tank and healer picks up on his greediness and not join to heal or tank, there’s so many other groups to heal or tank for without this kind of greediness.
Hopefully you are at least quiet about it and not announce to the whole world that you’re solipsist 
Despite not getting the helm, I got 2 pieces of BL on my first SV run
