maintenance on collectors
Have some rolling time limit where mines/pumps/drills get clogged and stop producing. Maybe like a 15 or 30 day reocurence. Will eliminate inactive members from being ATMs without deleting accounts. Could do a small resource bonus on "clearing" a collector so its not just a negative.
finding someone worth attacking is already hard enough
It is hard enough finding someone to attack that has enough resources to make it worth while. I spend a fortune searching for someone as is and all I ever find are either the th9's and 10's hanging out at the lower trophy levels or bases that have lots of one resource but little to none of the others. The last time I attacked it took me 35 trys to find one worth attacking.
