That sounds pretty good I have done something like that in the past last time thru I just direct attacked trying to get rid of the goblins using ranged attacks from height
I think the secret to your approach is to stay back far enough that he goblin archers can not reach you until a significant number have been eliminated, I’ll try but you might pass on a land mark where you keep your group back of to avoid marchers acid and fire attacks. I see from the photo your grease quite a way back and it would be nice to be am drow with the extra range they have.
