CWs: Loss of CPs when opponents leave on half

i think this should be fixed at last..
for example when a team win on a 9round match 7-2 on the 1st half ,the majority of the opponent clans is leaving so as not to loose CPs
and they take no penalties and the winning team get no clan points
clans leaving on the half SHOULD get a penalty or the winning team which remains on the room should get its CPs (and i believe CPs should be doubled when something like that happens)
i hope it should be taken into consideration by GMs...
