I would have posted this in the older skills thread but the most recent one was over a week old. From what we know (tentatively) about the skill system there is a trail period in place for skills that you can return them at cost for a period of time.
What if someone were to say buy their skills play for a while then sell them all back then wait until the next time they play to buy them again?
Just wondering if it might be easier to allow respeccing to your hearts content on the customize screen?
