It appears to me that the Shifting Tanzanite, one of the epic gems from Steamvault on Heroic mode, has not one but two errors in its stat allocation - firstly, being "Shifting", it should have Agility and Stamina on it, not Agility and Strength. Secondly, all other Tanzanites with Stamina on them seem to have their red stat listed first, and the blue stat listed second, with the red stat being the one that is higher than the Rare tier of the same gem, and the blue stat remaining the same - for instance, Glowing Nightseye is 5dmg/6stam, and Glowing Tanzanite is 6dmg/6stam.

In contrast to this, the Shifting Tanzanite not only does not have the correct stat types of agi/sta, but also has the stats in the wrong order - agi second, and str first, str being the stat that got upgraded from the Rare quality Shifting gem.

This being the case, what is the likelihood that this error will be noticed and corrected? It's been this way since Heroic mode instances were itemized, and hasn't been fixed yet. The reason I ask is this: there is no other way in the entire game to get a full DPS gem into a Blue socket, while still retaining the socket bonus (except for casters, since for some reason spell penetration is a Blue stat, go figure). So, on Red Belt of Battle, or Bracers of Eradication, putting this gem in that Blue socket would be the only way to gain the socket bonus without sacrificing DPS stats on the gem. However, if this gem is likely to be fixed (changed from 5str/4agi to the 5agi/6sta that it's supposed to have), then it's really not worth my time getting it anyway.
