One important note is that Flaming Arrows apply to Bow of War.
If you're playing an air nation, I think, it may be quite effective because one commander with BotW is nearly equal to 13 archers but he costs MUCH less in both basic cost and upkeep, doesn't need supply and can be given an Eye of Aiming. A drawback is, of course, that if he dies, it is also an equivalent of 13 archers
