Trouble with Flagged mission: Crystal Bravery

Hello. I am having trouble trying to get my squadron to meet the requirements of the L40 Flagged Mission: Crystal Bravery. The squadron that I'm using, their current stats are:
L45 Conjurer 26/124/34
L45 Archer 41/26/117
L45 Marauder 112/26/46
L45 Lancer 58/26/100
their combined stats are 337/322/357 . The stats I need are 315/325/340. I have used a spreadsheet to try to find a combination of training but I always end up with same stats as I begun. My other squad members are:
L40 Rogue 42/24/108
L40 Gladiator 96/24/54
L42 Conjurer 25/120/33
L41 Thamaturge 25/101/50
their combined stats are 288/389/305 . Any suggestions?

Just keep on training your squadron and send them onto lower leveled squadron missions to boost their level. Just remember that it doesn't matter what level your squadron members are as long as they meet all 3 stat requirements.

Heck, if you can't wait for 18 hours from gaining experience on squadron missions, you can do Command Mission dungeons if you have the company seals to spare. Your squadron members can gain fast experience this way too.
