Now before I say what I did, let me say in my defence that I spent 4 hours waiting on Mahamba, the first rare spawn I've tamed only to learn he isn't a unique model. Not wanting to be bothered to stable a pet, come back and tame Rak'shiri I just killed it. Gloated to my guild about my 4th rare tamed I was informed Rak'shiri is the rarer one, is this true?
