What about Boss fight? I doubt you can have 3 proper investment teams without premium currency spending or buying BP. It is the same situation with Expansion Drill 10. And we have pvp here you know. We should have some way to kill guys with v6 dolls
u mean lvl 50 boss fight? i saw people can just clear all boss just with 1 team (typhical maki, suom, qj, tololo)
he did 3 times every boss and just change his main team on every phase
so, in term of the content, u dont actually need to have 3 proper team
