I've got a realm full of alts with maxed professions, as I am sure many others do. This gets to be a source of some anxiety when a new expansion rolls around. I really like this class and this one, but I'd really need to level this profession. What can you do when your favorite alts don't correspond to your favorite professions?
Retraining a profession from scratch is pretty much the only option, but with all the rare pattern drops and whatnot, it really isn't an option. Plus it is much more enjoyable, and perhaps faster as well, to just keep you professions as is and spend the time to level an alt through new content than it is to grind old content and/or pay dearly for all the mats to relearn a profession.
So I had this brilliant idea that there should be a bind on account tome that you can purchase for gold (or possibly even real money in the blizzard store) that would allow you to record all of your patterns and skill points for a given profession (dropping the profession in the process) and relearning the profession on another toon by using the tome (in the process destroying it).
This would make it possible to move professions around your account quite easily (or at least one realm as BoA items currently work). Spend a decent sum of gold or a few bucks and you'll have your professions exactly as you'd like. I'd certainly shell out the gold/cash for that.
