Why is this even a thread? Let me make it really simple for everyone.
if all you ever do is roulette and pal around with your casual friends, no one cares if you DPS or not as a tank.
If you think for even a second a serious savage group is going to take and KEEP a turtle tank on staff that is too afraid to add to the groups DPS, you're sadly mistake.

So long as you Turtle tanks (Just threat and tank stance!) Are not interested in pushing serious content, none of this matters. the hardcore, midcore and raiding community do not care what you do. Try it in a savage raid though, and you'll get kicku.
