Were you folding for points or to help find a cure for cancer?
If the bigadv WUs are not producing the results they expected, why would you want them to continue? If they are not helping to find a cure for cancer you should be happy they are stopping!

Besides, everyone else is in the same boat, so you will keep the same position you have now
