I don't mean to sound jingoistic here, but this Q&A just seems to prove that people outside of the US just don't understand the basic fundamental game mechanics or the current leading theorycrafting behind tanking.
Asking about taunt missing? Thinking you need 5 tank spec tanks for the majority of TBC fights? Thinking you have to cap hit/expertise as a tank these days? What is wrong with these people?
... There are plenty of people in America that don't understand the basics of the game; [sarcasm]Even perusing the comments on the page, you'll find plenty of people with good old-fashioned American names, from honest, US servers, who brought up the threat/expertise issue. [/sarcasm] In my experience, the EU server community is more willing to experiment and try new things; take as an example Shaman raiding in vanilla: American servers were convinced that Shamans -had- to be Resto, even after the EU servers proved that a group built around an Enhancement Shaman would put out more dps than any other group composition (including another dps, or a Resto/Elemental Shaman plugged into the group). This was demonstrated with theorycraft and proven by logs, yet the American player base continued to shackle Shamans into their weakest spec (Healing throughput and efficiency were inferior even to a Paladin at the time) right up to the Burning Crusade. Do not even mention Level 40 Mana Potion Tide; you don't wanna go there.
