Sorry, was in a bit of a hurry when I posted that, and it wasn't clear at all what I was asking. Specifically, is the gamestage formula change just for loot, or is it for blood moons as well? There's definitely a difference in difficulty between, say, GS46 x 5 players and GS149, which was what we had that night. We were running Tier 3 weapons that night, and we still got rekt.
If we go into that same GS149 horde night and all we've got is tier 2s, we might as well split up the party and spread out to go solo. I get that there's efficiencies with a solid team communicating well and that means they're more effective than the same number of solo players, but not 300% more effective.
Also, didn't see that change in the "changed" or "fixed" list on the b155 announce post, so wanted to make sure it definitely made it.
