Pull with tomahawk.
If single target, do a HS>SS>BB combo, then alternate between storm's path/eye combos. To really get ahead you can use unchained on the pull.

AoE pulls, start with tom, Overpower, flash, and a steel cyclone.

Single or AoE, face the mobs away from the party. Except for the last boss of AK, don't do that.

With the changes to aggro, tanking is pretty mindless.
