While I don’t think FS is going to take the time to do this in a HD like capacity, didn’t we already have something like this to unlock the Ascension Riser mission? I don’t remember what the condition was, I think it was just getting kills in total, but in practice it has already been done.
And honestly that’s potentially why we haven’t seen more of it, because that event (rightfully) had huge backlash. However if this is the case I would assume it’s because FS didn’t identify the issue behind this, much like how they won’t nerf stuff because of the negative reception behind the Power Sword nerf.
They assume people don’t like community challenges, even though people didn’t like that because it potentially meant losing a mission if we failed; they assume we don’t like nerfs, even though it was mainly because they nerfed a really hard to get blessing that was really the only “fun” way to play power sword.
Found it, it was missions completed not enemies killed.
(I doubt FS would have let us fail the community event and therefore lock us out of a mission, but either way it wasn’t a great look.)
