My question is, can you farm lv10 npcs WITHOUT a war horn and still only get losses of 2-3k scouts and 4-6k archers each hit?

Those are the losses I have had so far using war horn, heroes with attack 180or more and an attack wave suggested to me by a fellow alliance member. If he is happy for me to post it and you are wondering what it was I might post it for you later.

PLEASE NOTE: I need a solution here that does not involve excalibur on the hero or anything else that has to be paid for.
