Patch 4.2 patch notes say
All existing Valor Points in the Currency tab have been converted to Justice Points. Any points above the Justice Point cap will be converted into gold at a rate of 47 silver per point and mailed to characters.
Is there any way I can flex that limit? I currently have just below max JP and want to maximise my buying power after the patch hits? Can I buy gear just prior to the patch then return it for a refund post-patch?
