385 Dark-Drinker with Weapons of Light and Tether.
It sounds simple, and it honestly is. Have 2 Titans run Weapons. one for the Canon-Users in Mid, and 1 to use Dark-Drinker against Aksis' Legs on Round 3.
I've been saying for over a week that Dark Drinker and Raze Lighter are the only exotics you need for the Raid. Now I can honestly say, JUST use Dark Drinker. It does more effective DPS, it does MORE DAMAGE than G-Horn and Sleeper Sim.
Datto has done the math, and can 110% verify the results.
At 384 Light, and being the highest-level member of my Raid-Team at the time, Dark Drinker did INSANE damage. I was the only person using it and we had him down to about 48% Health by DPS Round 2. That's 52% Health GONE in 2 rounds!
Get a Dark Drinker... And Deej? Bungie Devs? ... Leave. It. Alone.
Get your fingers OFF that Nerf Button, RIGHT NOW.

Without swords we had him down to 50% in the first dps phase, had an oh crap moment on the 2nd stun, no dps, then sent him to his final dps rage on the third round. We brought him down in 2 dps phases, use the cannons, all of them. I was 385, we had one 380 and the rest were in their 370's. DPS for teleport one and 2 was mostly snipers then unload on the final teleport. No swords needed just people that can output dps.
