Killed crota HM in a destinyLFG pug after about 10-15 tries, wasn't really too bad. Didn't use titan bubbles to block boomers, middle strat and had a pro ass hunter who was invisible most of the time. On the final round one guy was snipering boomers to make sure they don't hit the sword bearer. 3 Titans definitely helped though, we had bubbles for every time we went in and out of the crystal room and for protecting us during the ogre phase. Running into the right side ogre spawn room and destroying him and then snipering the other side is far, far, far easier than trying to deal with them on the stairs.
Its ridiculous though how much of a difference it makes having enough gallahorns and not, and how critical the sword bearer is to the fight. He is the superstar of Crota HM.
Until they nerf it at this point I don't really want to do the fight again, its just a lot of crap and frankly there isn't much responsibility for anyone except the sword bearer.
