Is this his only drop? Probably wouldn't matter. Other drops would have similar stats. This items only redeeming factor is that it is recommended level and not required. I could see using this on a character around lvl 30 for half stats. But would have to replace it by lvl 50 or so lol. I'm pretty sure there are much better back pieces that are easier to get. I mean of those classes listed who wants a 12ac back at level 65? This is a "lets gank this mob just for the fun of it" named =D
I may be crazy, but do any of the classes that can equip this item even have a mana bar? I have only played a War, but I am pretty sure none of the other classes use mana. Maybe including the bard class was intended, but forgot to be added?
It wouldnt be the first time Sony's made this mistake. It'll probably be wiped in some patch in the future, but I wouldn't worry about it. It just happens
