To be fair, there's plenty of them on AH's across a multitude of Realms, of varying Levels. I'm not saying yours doesn't have value, just pointing out it's not as rare as you might think.
Must only be one of few if any..
It must be mediocre in BGs, otherwise OP wouldn't be selling and would be using two instead (equipped: 1 shown in picture)
just trying to apply critical thinking, that's all.
All my pre SL level 20 freezing bands are ilvl 27. Only one had +4 frost resist. Levels 22, 24 and 25 rings are ilvl 29. I've only seen one freezing band listed on AH the past month.
