Really not sure what the thought process with this is. Even if it is easier, it's not a fast mission. Not in the sense of finishing it, nor in the sense of progression. Especially when the swapped mission is arguably worse.

Sad to see it. Given the small pool of items, many of which aren't even being sold, it seems like a simple thing to just let be.

Sad to see Legacy Fireteam Finder is on the list. It's significantly easier to invite people, and get exactly what you want. And likely will just result in people using Discord.
