Baa, I would not even worry about it. 99 Gear is sure to be better than this garbage.
The armor piece isn't going to be worthless, as SE has specifically said that they intend to keep from making a lot of the existing "top of the line" gear become obsolete. Whether that ends up happening or not is the question, but considering that the Nocturnus armor is basically available now, and the 99 cap is several months off, it'd be foolish to just up and ignore it because there might be something better coming out at the end of the year.
As for where the armor comes from, to be more specific it appears that it might come from a "Splitting Heirs" -esque Campaign Ops battle that becomes available once a nation takes control of Castle Zvahl in the past. Edited, Mar 28th 2010 10:24am by Vlorsutes
