hi, i may be wrong, but Army´s Paeon dosnt apply 10% Phys Debuff on Targets (No Debuff). It applys Phys Buff to Group. So i think Wander´s Minute in Opener is best choice.

This is true in a solo comp, but in a group comp, Ballad is the better choice; the increased crit buff to everyone else stacks with all other buffs/boss target debuffs to out weigh the damage you might put out from getting even two full 3stack repertoire pitch perfect shots out, if you some ungoldly RNG happens and you get 3x 3stack pitch perfects, then you *should* come out ahead, but, again it depends on RNG with crits from other party members.
