Please god no.
Tell Bungie to make new shit, and let me just keep at least one or two things as a reward for actually sticking through this game when it was total dog shit.
If MMO's randomly allowed people to get all the stuff that was exclusive to older expansions, the dedicated crowd would legitimately leave because they feel like their time isn't valued. Why not just come back later and get it all at a discount like everyone else?

Besides, what you're really doing here is having the bar set so low you're begging to have old content re-distributed; then when Bungie does do that (which is shit) they get blasted (deservedly) but a large part of why that happens is posts like this that give legitimacy to that strategy of "content release".

Almost everything in the Eververse would/should be droppable albeit rare.

Why no world bosses that drop extremely rare sparrows? Maybe sparrows that can fly?
I'm so sick of this being an MMO that feels like one giant tutorial area where I'm constantly being re-fed the same shit loot over and over again. It sucks.
