I have actually read a lot of them and there are far more of those that favor the shamans and druids than those that don't, same as with Alliance quests and their classes/races, not really a good point. Just read the books instead.
I agree Taurens wouldn't be able to conquer Ironforge(doubt anyone could) but then again they would never even try that.
If a war between these two races started it would happen in Mulgore most likely, because Taurens are known for being peaceful and have no reason to armor up and march on Ironforge, while Dwarves are highly interested in Mulgore and Barrens digging sites and would have an interest in claiming these territories.
So the battles would happen on the land that Taurens nourish and care about, a huge open field of Mulgore. And in this world that is one of the strongest sources of power, much stronger than the hand-made metal objects. I think it would look much like the Thrall vs Garrosh fight scene.
They weren't the strongest ground unit in wc3 for no reason, using their totems to pulverize anything especially if affected by Bloodlust.
