So ultimately what is the consensus on the best way for the team to deal with boomers when using the middle strat for Crota HM? I beat him once but we had a hunter swordbearer so most of the time he was invis so boomers were just ignored for the fight.
Yesterday I joined a friends group (after they were wiping for a few hours and lost a few people) and a warlock was running the sword. They tried a lot to have a titan to drop a bubble to block the boomer fire, but the titan would die a lot so they instead had one person shoot the boomers the whole time. It worked 80% of the time but sometimes the boomers would ignore everyone but the sword bearer while he was attacking crota or retreating and he would die.
Then they wanted two people to basically sniper the boomers and rotate killing one (not both, so wizards dont spawn) but that led to problems with crota's shield since not everyone had gallahorns. It fell apart after a few tries.
My takeaway was that its probably best having a hunter swordbearer, or if you have 2 people on sniper duty then you need the 3 people attacking crota to have gallahorns? Or is a combo of something like thorn + crotas hunger good enough? I wanted to help but they were tired and didn't really want to test out a bunch of different things. I tried a few times just shooting boomers with main gun and again about 75% of the time they would focus on me but sometimes they would attack the SB.
