I like throwing idea's out there and here very good one and could solve a problem. What about adding a configurable time that allows a base to be tnt'ed after the faction has logged out? Example: FactionA goes to bomb FactionB. Currently when FactionB realizes they are going to get bombed they just log off and have no reason to defend (This is with DisableTnTwhileoffline=true). If there was a time after FactionB logged off where FactionA could bomb it would encourage factions to stay online and defend their base's unlike what currently happens.
