wew...it took quite some time to get to the end of this heated conversation. Didn't expect this thread to be soo hot. But really, I'm quite amazed that in all that 2-3 pages of discussion regarding who is and who isn't and who can and who cannot be a shaman, nobody gave reference to far seer nobundo (for those who don't know who he is, he is a dranei holy paladin, a Vindicator in the Hand of Argus, in the dranei community when they still held grand cities like shattrah and karabor but became a broken during the siege of shattrah due to exposure to the blood mist and lost his ability to wield light but gained shamanic powers instead while being a broken not to mention how he was shunned by his own people whom he bravely defended that caused his deterioration in to a broken) as he gives u the perfect example of answering all those questions and as far as I understand the ordeal that he went through, it is that the elements only judge your worth as their vassal before opening up to u (which allows you to commune to them and wield their powers tldr; be a shaman) and not whether you are a beautiful or intelligent or experienced being / race that has ancient ties with communing with the elements / nature.
Anyways as far as the topic is concerned, dwarfs bruh no point in even doubting that. The tauren are too laid back for their own good. Of course they are a deadly foe if they are enraged but they are by far a very peaceful race that aims to maintain their status quo the same (other than one clan that is) while dwarfs dont have any such inhibitions and get easily triggered thanks to the political scheming that their leaders are used to. (proved by the extreme infighting between the clans)
This is just one man's humble opinion anyways. Ultimately if Chris decides to make tauren wipe out ironforge even though its logically impossible, I'm sure he will find some excuse to do that (although that would be destroying the product).
