Hi, I've done 25 man progression so I'm not too sure how well the checks will go for you.
Make a targetting macro and put it on a keybind that's very easy to spam. I've got my targetting macro as the mouse button closest to my thumb (MB4).
Here's my targetting macro for T15
Code:
/tar Lei Shen
/tar Zandalari Dinomancer
/tar Blessed Loa
/tar Shadowed Loa
/tar Suen
/tar Dark Animus
/tar Durumu
/tar Essence of Anima
/tar Corrupted Anima
/tar Vampiric
/tar Unharnessed
/tar Crimson
Feel free to add Crackling Stalker BEFORE the Anima orbs on the macro or you'll always target the Stalker that's up while orbs go out.
I've play all three specs for the fight (Only kills with BM and MM). If you choose BM, I'd recommend using Fervor/Blink Strikes. I prefer Fervor for this fight since boss damage doesn't matter and Dire Beast won't be very effective versus the orbs and if you do use it on orbs, then it will have to deal with travel time, limiting effectiveness. If you can manage the micromanagement, toggle Dash off and make a macro so you command your pet to dash.
You want to alternate your Glaive Toss on Orbs and Boss/Stalkers.
For example:
Glaive Toss 1: Boss
Glaive Toss 2: Orb
Glaive Toss 3: Boss
I'd recommend putting a /petattack line in a Glaive Toss macro if you haven't already.
Code:
#showtooltip Glaive Toss
/cast Glaive Toss
/petattack
/petassist
/use 6
Here's the WeakAura we made for Materials of Creation cast (it's very obnoxious and gets the job done).
Code:

When you hear the Air horn go off, you've got about 2 seconds to get under the boss to be central to all spawns, ready your macro, and start firing. With the range of Blink Strikes nerfed to 30 yards, you'll have about 2-3 GCDs before your pet can touch the orb (Kill Command range is 25 yards). Your orb rotation will look something like: GT > AS > AS > KC > Fervor > AS > AS, etc. It's imperative you don't mess up your Fervor timing since the orbs are every 32(?) seconds apart or you might focus starve during your Arcane Shot dump. As the first orbs come out, I'll blow Fervor on the second GCD regardless if I need the focus or not.
MM can actually be pretty viable for this fight if you play is smart. You've got a long Careful Aim phase and you'll always get a huge crit from Aimed Shot on each and every orb. I'd recommend Fervor and AMoC for this spec. Additionally, don't use that Glaive Toss macro from before and let your pet tunnel the boss or adds, it's not worth losing the DPS from your pet on the move.
The basic premise of this spec is to sit on Instant Aimed Shot procs as the Materials of Creation timer is about to go off. WeakAura goes off, you hit your target macro, AiS > CS > GT > Fervor > AS > AS etc. Only thing that really sucks for this is the need to recast Aimed Shot on the boss since every third Chimera Shot will go to the orb (If you can make the DPS check on orbs, you can drop CS on the orbs and leave it for refreshing SrS on the boss.)
One thing I don't like about MM is the difficulty of getting Hunter's Mark on targets which is why I have CS before GT on the orbs. If you feel the need to attack Crackling Stalkers, do it during Careful Aim phase (Steady Shot until 80% and switch off) and during Kill Shot phase.
Additionally, don't be frightened by MM because of how clunky AiS can be. Outside of Careful Aim phase, you never have to hardcast Aimed Shot (including during Haste effects). Feel free to Arcane Shot dump during that P2 Rapid Fire if you feel you'll be more comfortable with it.
Here are logs when I was MM:

Disclaimer: Don't go MM and tell your raid leader is best. Test it on a few pulls, if it's not working then switch back to BM. BM will outperform MM it's just that MM is slightly viable for this fight.
