IFSC can not afford cancelled events any longer

Several of the finalists in Wujiang were upset about the cancellation of a final again in China and said unofficially that they will not compete in China next year. Most of the athletes spend a full day travelling from Europe and then they are not allowed to climb a final in fair conditions or to climb the final at all. As this has also happened in Europe, it is time for IFSC to either have all events indoors or to really cover the walls so it is possible to compete also during heavy rain. Do you know any other sports, beside regatta sailing and snow sports, where cancellation like this happens as often as in climbing?
