Threat on Moggle King EX

When I tank Moggle EX, I build lots of threat in pre-phase, then never target the king except to provoke him and throw a tomahawk. I have never lost aggro to the king without the other tank provoking. I generally spam Storm (heal and atk down) rather than the threat combo on my moogle since staying the threat wipes are the only time threat matters.

My question is that somehow the OTHER tank will lose the king back to me, without me targeting the king or him dying. Is it possible I'm getting threat from my self heals? What should my other tank do to keep the king on his side?

He should just throw up a threat combo on it, and solidify with some aoe.

just to be safe, when your turn to tank King put like 1 hate combo on him.
also, All the CD / BUff have some small amount of agro attach to them when you popping them.

He's just voking. As stated above ask him to follow the voke up with lob or a combo.

I put up Storm's Path on King as well, to help mitigate dmg as well as secure him.
