Yeah, it seems like once you get past 350k total power the number of stages that become difficult to clear largely dwindles down to those connected to whichever nation you have the fewest members of (Winter Rose Garden used to be a thorn in my side even when there were only three sets of stages to work through) and the fourth/fifth stages of each whale ship mission.

yea, might not be as strong as the account on offer, but for me, do not have time for two accounts. One account is all the time i want to invest in this game, and not going to abandoning my own account.
