Just to say one more thing. I believe you can have WHM spam aoe to get highest threat as much as possible. By then, pld / war can provoke and whm use shroud of saint right after.

Reason?
1) Provoke make your enmity to highest, just above the previous one.
2) Shroud reduce current enmity by half.

Just make sure, your tank don't waste provoke in a wrong time.
