some TBC/WotLK enchants were rated badly, it should be ok now, thanks for report. However, there are still some cases where TBC enchants are better than WotLK, depending on it's value for specific class.
Had the same thing happen tonight on my boots, added icewalker and on first check it showed +15 as advertised, when I checked again WowHeros showed 0 points and only showed icewalker enchant when you moused over the enchant column by the boots. weird but I like the enchant even without the points.
