How can I tank multiple mobsFollow

When it does break though, it runs straight for the CCers. Also, have you done Kara? There are plenty (most) of pulls in there where you just don't have the room for that kind of spacing.

TC, Demo, peircing howl, and Cleave, cleave, cleave imo. 8/12/41 is a really nice spec for anything but the big raid bosses imo. nice boost to some of your AOE abiltys( imp demo and 1 in imp cleave) i gave up imp HS, imp taunt, and 2 im vitality to get the 7 more on fury tree. only notice the imp HS on bosses, the 2 in vitality arent noticable, and imp taunt.. lol, taunt is for amatuers and low lvls. alot of raid mobs and most raid bosses imune to taunt so its good to get used to not using it at all.

Technically TC would raise your overall threat on the main target. If you were multi-mob tanking without it, you would still be using GCD on another target to Shield Slam, or Devastate, or something. Using it on a non-focus target doesn't magically negate the fact that it still takes a CD rotation. The difference between TC and those other abilities is that while the others do not hit your primary target as well, TC does. In a multi-mob situation, TC does nothing but increase your overall threat.
