I have the exalted tanking ring on my toon. Is it possible to buy the exalted DPS one via Warmane Store and aquire both at the same time? I know sometimes duplicates can occur. (did onyxia head quest on both horde and alliance on the same toon, now I have 2xOnyxia tanking trinkets that stack), and seeing as the rings have unique names, perhaps you could have mulitple if you bought them for coins? :)
Same question (sorta) for Shadowmourne.
Can you buy it for coins, and later do the Quest and have 2 (they are unique, so I know you cant equip them at the same time on a fury warr forexample), but could I have 1 for tanking spec and 1 for DPS spec on my DK? :P
