here is the message blizzard will send to you. A warrior in my guild had 450engy / 450 mining. Heres what blizz sent him.
"When you opted to revert your version of the game from this caused some confusion between the system and your account.
As your character was level 60, any impact on the level of your character did not cause any difficulty with logging into the game, or skill/level confusion on our end. I have seen players that were leveled up past 60 and also ones that had not been, though they had logged out in an area that their clients no longer had access to (I.E. Area 52).
So the good news is that your character itself is in good condition. However as your professions has been brought up past the skill level beyond where a standard box edition would have access to (i.e. Master level as the trainers are in Burning Crusade areas) it is clear to us that a bug report is required to look into the reasons for why the system opted to offer you some skills that should not have been available to you post Burning Crusade Trial.
At this time we are not going to be further reverting any of your learned professions any further as this was the skills that were available to you according to our server's system records. Regrettably this same issue is why we will not be able to offer any additional recovery of skills or schematics in this case, as you would need an upgrade for Burning Crusade or Wrath of the Lich King client.
I have also discussed your request for monetary compensation for having purchased the MOLL-E. Our current policy is that we are not able to offer restorations for content changes. In a way the choice to have this account reverted to an original client version is effectively a content change. As such I was not authorized to offer you any monetary compensation.
I can imagine that this sort of situation was not something that you had foreseen when you were making the decision as to keeping the Wrath of the Lich King and the Burning Crusade expansions or to request a refund. However our policies are created with the need to keep the integrity of the game and all parties by insuring a fair and level playing field as outlined by the developers.
Thank you for your time and understanding of our position in this matter. If you have any additional questions for me you can continue contacting me and I will answer you to the best of my ability. Furthermore if you would like to leave feedback about the policies, the reasons why we were not able to assist you with additional recoveries, or even leave a message for my supervisor (as well as all of the Customer support staff) please e-mail
