Either way, just keep farming with minimal loss.
Example, if you are farming every 15 mins a villa with 5 clubs, you can raid 300 recs. If you are only getting 100 recs, you should adjust to keep loss to a minimum.
Adjust the raid amount to 2 clubs, and get 100/120 recs
Focus on don't losing troops, keep a good army.
