It would be so Bungie of them to try to take 5 coins off the loot table only to boost drop rate of 9+ strange coins. It's not right though because if you run the Weekly Heroic it gives you 9 strange coins. Nightfall is a notch above that. Should give you minimum 12 strange coins or other loot.
But yeah, I have a feeling the intention is so people would stop going crazy over only getting less than 9 strange coins for a nightfall.
you already know thats what theyre gonna do. just like the "we will make sure purple items from the cryptarch will turn into legendaries more often" thing. they didnt tell us they made it so we'd RARELY get purple items from the cryptarch at all now. (not to mention there is no noticeable difference in purple engrams actually turning into legendaries) so if theyre making it so that we'll get 9+ instead of the occasional 5... just know we'll see 9 A LOT more often now.
and nah bruh. the intention is to make stretch the game out even more by giving us weapons at an even slower rate, effectively getting them closer to that 10 year goal. the guise/lie/latent function is so that they address our complaints about getting 5 coins. but we're hip to the game by now lol.
