Pop into the Destiny 2 Eververse Store today and you'll notice that they've got something special on sale: The Iron Emote Bundle, "a limited-time bundle for Guardians who remember the Iron Lords." It contains one Fireteam Medallion, one Gleaming Boon of the Crucible, and the kicker, an Iron Lord Exotic emote called "Salute of the Lords." It's available for direct purchase for 1100 silver, which works out to $10 in real money. Sorry, bright dust not accepted.

Basically what you're looking at, then, is a $10 emote, and that's not going over super-well in all parts of the D2 community. As the original post in this Reddit thread says, "Locking it off behind a $10 paywall would be one of the dumbest moves to pull at this stage in the community/developer trust rebuilding. This isn't some random sparkly emote, this is the goddamned IRON LORDS WE'RE TALKING ABOUT."
