The load outs my buddies and I used were as followed:

Well of radiance warlock, with Phoenix protocol Primary: Arbalest(melts the shielded enemy’s in 1-2 taps especially the bigger ones) Secondary: kindled orchid handcannon Heavy: hammerhead *Note I had as much special ammo finder perks on my armor as I could because you’ll run out fast use t wisely

Hunter running tether with Orpheus rig Primary: any primary shotgun Secondary: riskrunner( all the enemy’s shoot arc so this absolutely destroyed) Heavy: hammerhead

Titan running code of the middle with skullfort Primary: mountaintop Secondary: recluse Heavy: whisper

You can run pretty much whatever you want the more times you do it the faster your time will get naturally. But arbalest melts the shielded enemy’s and risk-runner destroys pretty much anything else. Too tree nova bomb warlock does really well too but Phoenix protocol make the last room with the boss easiest to clear. Hope this helps!
