I can confirm mine is the correct team, yes. Btw, Ive had an idea for a while and that is that unpromoted units can be given 100 EXP worth of BEXP and promoted units only get 50.
Marcia delays chapter 4 and chapter 9 too and shes not that good in Chapter 12 thanks to BEXP limits. Idk, both are good but the logical choice is Marcia probably. Jill is much better after Chapter 24 though as she never stops ORKO'ing.
