I am the person who uploaded the Spirit Healer and Molten Giant (found in Molten Core on WoW). Sadly an admin deleted the model saying its against the rules, even though i put it in the WoW model section like it was suppose to go, and it was a model from WoW.
Its a common sense thing: Units traditionally have around the hundreds, the heroes are in the upper hundreds/lower thousands, and the special campaign showoff things are in the thousands
But did you remove the unessesary geosets from the Spirit Healer? And why not just leave the "Magma" giant with the common Mountain Giant skin, like its Arathi and Marudin variants? /shrug
