I was being greedy, that's all. Apparently my participation status affected the roster.
Choice 1:
Core: RM, John
Subs: Azrey (I won't be in the team)
Choice 2:
Core: Me, John
Subs: RM (If I can't be on, RM cores)
Result: I chose 2, RM rejects the sub spot then leaves. John and RM were a package deal.
And I believe we are just back to Alumni vs Apostles vs Immortal. Idk why Alumni tried to join Immortal when they have a good list of their own crews?
