I always thought when a character had a passive beneficial effect - ex ATK increase from the Nomad, Wickerman, or Alliance General - it was all-or-nothing. There or not there.
Noticed today as I was playing my Tailgunner Eddie hit harder - sometimes significantly harder - with the ATK boost from the Nomad as opposed to the Alliance General. Will try a Trooper's Wickerman tonight
So then it becomes trial-and-error if two characters boost the same stat.
Anyone notice this in any other buffs?
