We know that workflow rule evaluation criteria can be confusing. So, in Winter ’13, we simplified the text and reordered the options to show the simplest one first, and the most complex one last. NOTE: The default setting hasn’t changed, but it’s now the last option in the list.
However, based on customer feedback on those changes, we changed the text again in Winter ’13 to be more descriptive. We also added the “How do I choose?” link back in, but it now points to a more relevant help topic.
