I know there will be a release of the Unlearning skills, but would you ever consider stopping your Magic Rock in order to leave room for the new skills that may be coming out? I say this because I recall in Beta when learning times actually went up to 15 days for me due to being over BL skill limit.
If we wait for the new skills, they will be considerably less time taken and we can always turn to the auction house for stuff that we aren't able to produce ourselves.
