Friendly challenge settings

Disappointed with the friendly challenge update. IMO you should have a setting where if a higher TH is challenging a lower TH, the troops should be limited to the defending TH. For example if TH17 is challenging TH15, the troops should be maxed to 320, the troops and spell levels should be maxed for TH15, the equipment should be maxed to 24 and so on. We need to make friendly challenges fun and challenging even when you attack a much lower TH.
