That's good news for me, since I won't have to level any toons to keep my profession armada afloat. I may decide to push my hunter from 70 -> 75 just to be safe, but if the minimum level is 70 I'll be positioned to continue my trend of self-reliance into the expansion.
All my alts (that I'm leveling) are up to 450 cooking so no probs there. Main is max LW/skin at 450, tailor/chanter is most of the way there (425+), alchy/herb is 450, JC/mine 450 and engineer/mine 425+. Fishing needs some work by everyone but my main with all the alts hovering between 325 and 440. First aid is the only bad skill - no one has gone past 375 due to all the cloth going to the tailoring alt.
