There is no reward for intentionally failing though, that's the point. By agreeing to fail the leve, we who do lose the chance to be awarded any reward/faction points/gil associated with completing the leve. By forfeiting our rewards, we have the option to re-do the leve during the next reset.
There is nothing wrong with this action, regardless of some players having issues with it, it was installed by SE and has been constantly proven to be an acceptable practice.
