It's a boring and ugly reward for a heavy grind achievement. The only reason I would bother leveling to 90 for every class is to ensure they are ready for leveling in the next expansion, on the off chance the reward won't completely suck next time.

Once I earn this reward I will be discarding it to save inventory and glamour slots. If you want the headpiece for glamours? Just go to Qitana Ravel and get any of the headpieces from there. Basically the same thing. Junk item.
