A way to minimise the effect of team orders is to award a proportion of the championship points on any event for each stage won. This would have minimised the benefit to any driver who is 'allowed' a win on the final day / stage. I haven't thought through the ramifications, but if, as our Hellenic friend pointed out, Ogier was sandbagging Sordo then he would have been giving up points by not trying to win every stage he could.
