Not entirely sure I agree with this one, but for one sole reason. Getting hit by strong AoE isn't generally wise in any circumstance. A smart tank will be able to move out of the attack range and slide back into position while their attack animation plays out, both avoiding the damage AND keeping the mob relatively stable. At least, that's what I do.

This way you both minimize the damage, which is a tanks primary job, and make things far less bothersome for positional attacks from your melee.
