The class useable list needs to be updated a bit. It is useable by all chain and plate class: WAR, CLR, PAL, RNG, SHD, BRD, ROG, SHM, and BER. THe picture is also a bit out of date not showing berserker as useable class. I can confirm these classes I listed can use this armor today.
And since no rec. or req. level as of today, probably the best twink armor in game.
