Gnomish Battle Goggles

Forget about these! Unless you absolutely positively have to have this level of goggles before you hit 70, save your mats and wait until you get a primal nether and get the X11 Deathblow's instead.

Seriously: don't waste all these mats on this Head gear. Unless you plan to hardcore twink before 60 or want some headgear that will last you through the 60-70 run (plus have the mats lying about) then get these.

Anything beyond that: I personally don't think this level of mat requirement justifies this helm. Too mediocre and there's a ton of greens and instance blues that can easily fill this slot.

These are fantastic for getting an alt through the 50-58 leveling slump, and are quite useful until you can equip the ones that require level 62. Plus the mats are easily farmed and/or cheap as dirt in the AH now that Outlands stuff is considered worthless.
