Seriously. Bungie only got away with it in the first place because we eventually stopped talking about how stupid and greedy it was.
TFS is a great DLC, perhaps the single best release this franchise has ever seen, but don't let it distract you from how greedy and user-unfriendly Bungie's business model has become in the last few years.
Remember the first annual pass in Forsaken, when they decided we wouldn't be allowed to buy seasons individually? If you wanted one, you had to buy all of them.
Transmog limits you to a certain amount of uses per season, unless you buy silver to use it.
In-game services such as level up packs and the dungeon keys have to be purchased with silver, which goes on sale significantly less often than products on the steam page.
You don't have to visit the actual eververse vendor to decrypt bright engrams. No other engram in the game has this functionality.
And dungeons, which used to either be free, or come with their connected DLC, are locked behind their own paywall.
All of these are problematic, but the most problematic issue is definitely the existence of dungeon keys.
They should not cost $20 a piece. That is ridiculous considering a DLC for the game is $50.
The most important thing is that we don't stop talking about it. Ever. At least until Bungie acknowledges it. Force them to at least make some kind of statement regarding it.
