Rather easy HM Crota Strategy

Urgh I saw this last week on reddit, and tried it a few times with a PUG. It went HORRIBLY! Thrall will run up to bubble and kill team. Gatekeeper will run up to bubble and kill team. Boomers on 2nd floor towers will SHOOT THROUGH THE F-ING FLOOR and kill ppl on ogre door frames. As Crota moves to a side and team gets ready to leave ogre room, Crota will drop down to 1st floor and kill everyone (I have video proof!) And of course, people will shoot rockets in bubble / at the backs of other teammates and die. I've finished CE hard mode 5 times now. I strongly prefer the extremely popular "center lip" strategy: 1. touch crystal and kill enemies (not 100% necessary to generate orbs, but definitely helps) 2. everybody gets ready to leave room (left or right sides don't matter); leave together. 3. everyone goes to center lip and snipe-stuns Swordbearer. Once it reaches half health, team's sword bearer goes down to the top of stairs (but behind the right door pillar for cover). 4. sword bearer grabs sword, and goes to the right rock. 1+ teammates distract right side boomers (snipe them from lip; bubble on right platform near lip and pop up to shoot; go behind tower's far wall and shoot; etc). 3 smashes + 3-4 smashes. Crota's shield can be taken down by 3 lvl 32 w/ max ghorns or 5 lvl 32 w/ max hunger of crotas. After shooting your rocket, switch to primary and keep doing damage. 5. everyone on the center lip move to the left portion of the lip, and hide behind the vertical divider. NO ONE SHOOTS ANYTHING. Wait 1 min. Sword bearer runs to right side ogre room and hides up on a door frame. 6. once Crota moves back to center, sword bearer (mate) shoots Swordbearer (mob) and aggros it. Then sword bearer runs through the center and jump up to platform near lip while everyone kills Swordbearer. 7. repeat step 4 8. everyone goes to right ogre room and ganks right-side ogre as it comes out. Only shoot a rocket if it is now coming out of the door beneath you. DO NOT JUMP AND SHOOT ROCKET or you will die due to hanging chandeliers. Then snipe+rocket the left-side ogre (good to have Blessing of Light bubble for safety) 9. depending on speed of team, either all run into Ir Yut room if Crota is already at center, or go to center lip if Crota is still on left side. Kill Swordbearer when it spawns. 10. repeat step 4. Final step caveats: move as far away from glass wall as possible while on the center lip. Thralls can swipe through the windows. Also, once Crota enrages, DO NOT PANIC and IGNORE OVERSOUL. Make sure you have 2+ rockets ready to fire at Crota. Count down from 3 after Crota gets up to wait for its yellow shield to go away, then fire all heavy + primaries. 11. PROFIT + Glowhoo! Benefits vs 2-bubble side strategy: - takes down sword bearer much faster = less ads on floor and less chance of Crota enraging due to timer - less time spent in Ogre room means less likely to be glitch-killed by boomers above you - center lip is immune to boomers, Gatekeepers, thralls, ... - greater situational awareness of the entire battlefield - ideal setup only requires 1 titan and 1 hunter.
