I Have Crew Training Books. Should I....

TeriyakiTanker: In my opinion you might as well just use them.  As of right now Crew 2.0 is going back to the drawing board and no one knows when or if it will be released or even what it will look like at this point.  I would just suggest using them on the crews you want now and not even worry about Crew 2.0 until we have some more information on it.
