Hiya
I reached rank 10 on my undead mage back in the days and can transmog a full epic lvl60 set. I also bought the weapons that I was able to equip.
I also can transmog a full epic lvl60 set on my newly created human mage and the weapons can be transmoged by any of my chars.
I find it strange that I should be able to equip sets cross factions....
Is this how it is supposed to work?
