Should I save a lot of pero for this event or is it not going to be used as much. I have a method when teasing others where I hold the mouse in one spot to click all the buttons and then move it to the far right and pick one of their friends, rinse and repeat. I used a lot of pero trying to get those limited cards from last event and have 36k~ left. Also I'm focusing my missions on the ones that gives money to buy gacha which I find is better than buying more N wilds from the store because you have a decent chance at getting SRs and Rs leveled up as well.
