I'm glad you enjoyed yourself in frontlines!

I always find it fun to Collective Unconsciosness, then Spread Bole/Balance and Focalization and then Celestial Opposition and turn my whole party into a monstrosity to face off against personally. I bled, sweated, and cried my way through 100 seal rocks for my Field Commander's Coat to the point where frontlines became really easy to manage myself in. (I finished at about 350 total frontlines, 119 wins, so just under 1/3 win rate)
