You definitely have a point. When me and a buddy were doing crimson doubles we went in with shotguns and what ever primary we wanted. How ever quiet a few matches we were paired against icebreakers, and yes it was disheartening, but it's now a viable weapon for the regen of ammo. It's sad to see people exploit a simple mechanic of the game for some stupid reason, but it's what ever. As for the gally and oryx I'd love to know that too. I know datto did up to the war priest with fatebringer and gally. Said it was really difficult and stopped after I think 8 hours and a wipe at the war priest.
