Legion-5 shrugged and said, "We just have to make sure they lose something too. That way, we might lose the battle, but we will surely win the war."
Legion-3 wasn't completely accepting of their impending loss to their mortal army, but there was nothing they could do to turn the tide.
So he said, "5 domain gods is not too bad for the lives of 200,000 mortals. I just have to make sure that their death is worth it."
He is the one with Golden Light. Unlike the divine realm, their inventory doesn't work here. So they had to bestow the divine weapon to the mortal realm in advance, and only one of them can use it.
He is the one they chose to make the domain gods pay for the lives of orcs that will be lost. As for the rest of the clones, their job is to resume what Legion-1 started.
So all of them flew in the direction of the capital. They didn't go to rescue the orcs that were being massacred because that is a foolish decision.
