I'm currently catching up on the submarine train. I got them all max with all except the last newest zone unlocked but never upgraded from CYYY at the end of Stormblood. That leaves me at 160 Surv, 170 with bonus. I know I technically need 190 and with CYU+Y I do get to 180+10 reach the minimum for Meerkats technically...right? Eventually feel like CUUY upgrading the first three would be my goal but for now, would that suffice? Thanks for the help.
