Crota killed with a 4 man team ! :) ill add more tips and a full description if this gets a lot of views and people want to know and understand the tactic and strategy being used. In the crystal room we had 2 looking the opposite way of each other taking care of both sides of acolytes and knights around the same time. 3 guardians went down to the right to snipe the boomers on top, one guardian went towards the left to get the chalice, boomers should be dead so he can come in the right room safe. For this strategy to have worked for us we had to have two titans at least. Both with Weapons Of Light. One titan would pop one bubble at the corner on top of the stairs while the other pops a bubble on top of the rocks you see in the video. The steps that I mentioned above should only be happening around the time the swordbearer is about to go down so the bubble doesnt go away fast. Hunters job For this to work a hunter will need bladedancer, with the perks "ShadowJack", "stalker" & "escape artist". Once the swordbearer goes down you need to have had a super already built up so you can go bladedance as soon as you pick up the sword. (This helps with agility) once you grab the sword youd want to head towards the rocks with the titan bubble crouch down untill your invisible and get RIGHT next to crota thats when you tell your team to shoot crota down as soon as hes in his animation going down you tap R2 (how many times your comfortable Hitting him) when hes getting back up you drop the sword and blink strike him making yourself instantly indivisible so he wont kill you, pick up the sword tell your team to drop his shields and thats your second pass. You wont have a blink strike so the second pass had to be played out carefully. Now you just rinse and repeat, you only want to do all this when he's in the middle not when hes on the left and right platforms. I should also note that we ALWAYS had one person dealing with the boomers on top.
