I feel you on that, though I feel like if a character deserves to be upgraded to main girl my vote would be Ami (as of now, who knows what you'll add next) hands down. Though if the choice came down to getting more main girl content like Chloe, Astera, and (as of this patch, yay!) Qarinah I'm down to just sit on my hands lol.
Though I'll let the experts work and I'll enjoy the ride regardless as I have been since the day this dropped. Keep it up enjoy your vacation.
