This new system would ensure people get credit and there will be no excuse for throwing explosives on people other than to be an ass.
What if NWI did a chain rigging where the click goes to the "last person to "FINISH" rigging. Player A, B, C
player A begins rigging the cache. Player B realizes it and joins and begins rigging. The clacker then goes to player B. Since A started it and once finished will have only placed explosives. Player B can set it off once he/she finishes rigging. Player C walks into the room wants to get credit and begins rigging after player A and B were walking out of the room. Player C finishes and sets it off on himself he would have been the last to rig.
If a person with clacker dies the chain works backward until someone new rigs it.
This might sound like a long process but in reality, it would be very short.
