Freeze mage ? what are you people on lol, freeze would never run this if it had even better stats. Might see play in Hunter for sure, would have certainly seen play if it had the beast tag. I think it's pretty good.
Because it's considered a statue, like Spectral Spider isn't considered a Beast because it's a ghost. Although, they have screwed up Beast synergy in the past, like when Silithid Swarmer wasn't made a Beast until recently.
