At TH7, if you're trying to farm for resources, it wouldn't make much sense to use any other troops, or have any other strategy besides constantly 3-starring town hall 5s and 6s with all dragon armies, losing at most 1-2 dragons per attack. You find bases with the air defense on the outside, and you won't lose any, so it doesn't even matter that they have virtually no resources because you're not losing any on your attack, and you get to go right back in when you're done. At lower levels, the pool of bases you'd be able to attack would dry up very quickly.
The only way to avoid this would be to basically alter the entire game and throw out the entire trophy system, matching on level instead.
