So how exactly do coop alts work? Doesn't that make them complete trash for farming? I tend to do alts only under very specific circumstances based on the time of day it is, how much stamina I have, and how far I have until rank up. Finding a partner quickly during those extremely specific times is going to be nearly impossible. Or is there some kind of partner matchmaking? Or are they still plausible to run solo?
And yeah, challenge descends would be great, but mostly we just get more trash jewels lately. At the very least I want some snowglobes, since I'm back to having none at all, but Yamato Challenge didn't even have those. The reward may as well be carbuncles at this point for how much I need more jewels.
