Ended up getting 2 5* Takumi's whom proceed to destroy everything in their warpath. Getting quite a few defense wins as many cannot single round a Takumi. With countenance he will take any unit to half and kill shot in the follow up(If not immediately killed in their attack round).
I get that archers have a bonus against flying units but they almost always 1 shot the unit unless they have >55HP. Why even create these units if a single archer will annihilate them in a single round. I'll never understand the point of flying units with such a large disadvantage is on the field.
