Note: On a $3/$4 opening, you have one less Wayfare turn when putting it on Spring, but also your first buy makes it into the shuffle, meaning you can make better use of Wayfare. I see there's a difference, but it's not as bad as you make it sound. Also, the action bonus already means that you lose part of its power in Spring, as Co0kieL0rd said. That said, ii'd rather not have Wayfare at all than have it require a mat.
