The transmutable new adept-spellbooks (lvl 111-120) give outdated rewards. The transmuting result is not from the currently xpac and not from the pre-xpac. It is from the pre-pre-xpac.
Adepts in BoL still give outdated fragments from 2 expansions ago. Can nothing to do with tradeskills be fixed, or work properly in BoL? This has been an issue since beta, maybe someone could give a crap about tradeskills and fix it.
*bump* Almost 5 MONTHS later, and this bug still hasn't been fixed.. or even formally acknowledged. Edit: And, yes, I did just test it to make sure it wasn't ninja fixed.
