Though Tauren are built strong...they are not the war bred like orcs. Yes Orcs do have a shamanistic background the Orcs history is filled with tribal warfare and then, let's not forget, infused with demonic blood. Where as the Tauren have led a predominant Shamanistic lifestyle. Hence, my treehugger comment earlier. But Blizzard keeps changing stats eack expansion on every race so certain races will get a new strength buff each time. I bet the next one you will find the gnomes to be stronger than anyone (sarcasm).
