Currently the skill is arguably useless. With the AI 2.0 introduced, any avatar equipped with a shield is likely to be targeted last, and even with taunt it doesn't guarantee they will be targeted. Ideally the ability needs to guarantee targeting. Then last more turns or be able to be used through an enemies armour to make it not useless.

This skill needs to be useful for tank builds to be viable. As this ability is currently a crap tier skill, any kind of avatar equipped with a shield and taunt is behaving more like the Stench talent and being ignored by the AI. Which I don't think was the developers intention?
