Usually those fail attackers do not take much of resources and its hard to see it, but in fact they steal resources too. And sometimes it is alot and more than those traps.
BHG not only ignores fixing this exploit which became massive, but does everything to motivate users doing it more often. Huge medal losses on attack is one thing. Secondly, they allow taking resources. And yes, since they can't fix it for so long, Aussie offered a free recharge of traps and I offered a cheap blessing which autorecharges traps for lets say 12 hours. Or give a PT after any attack at least.
This bug alone makes traps useless as well as defense, because if one attacker fails, the second one immidiately crashes your base without traps.
