The cop out answer is it's up to you. They're your stones to spend. Dios is an incredibly valuable farming tool, but his dungeon is in the rotation and will come back around again. Keep in mind he's not that great until he's in his final form too.
Do you see a significant benefit to being able to farm MP or rogue bosses? If so then it's probably worth it in the long run.
I think it might be, honestly. My green row team as it exists now is pretty well able to stand up to anything I throw it at, as long as the guy who posts the room has 3-4 farmed up Zeuses. I think it'd be much better for me if I could be the one advertising my own ALB team with farmed up Zeuses in order to take out content at my own pace.
The main reason I'm hesitant is because I often see backlash directed towards people who advertise ALB teams without Liu Bei as the leader, like when people sub in a Perseus, or Australis. I've seen people join other people's rooms and rage quit after seeing their leader and then call them out in the Discord chat for misrepresenting their team. So I'm not sure if it'll be worth it for me to go thru all the effort to make an "ALB" team without ALB, when my team as it is now is already good enough to piggyback on a real ALB team.
I think I'll let my stamina tick up a bunch regularly during football today and run when I can then see how close I get to maxing one out and maybe buy some stamina to continue tonight if I need to. I think if I just sit back and accept that most things you accomplish in this game are going to be multi-week endeavors unless you're willing to keep feeding it quarters I can just let it go for now wait for the descend to come around again in a couple weeks.
