I've not had a problem finding a group and I insist on doing everything legitimately. No returning to orbit so they can cheese the boss BS, that method is dumb and troublesome. You could beat the boss legit in the same amount of time it takes for that one guy to get him in place to fall off -_-; First time someone started doing that I snapped and said we're just gonna do it normal. Immediately they were like "we dun know how" I showed them, we did it our second try. Piece of cake. Been running with that same group ever since give or take a couple fills.
As for hunters, the first people to down the raid had a group with five hunters. So tell that to anyone who complains about hunters next time. Stealthing for the relic in gatekeeper is straight up pro.
