Im kinda lost of what you said lol. Tank has the skills and routine to generate and secure hate from a single or multiple aggro beforehand, they also have a defense buff skill to help the healers not to spam high tier cures. I don't see how WHM will grab a lot of hate and aggro if the Tank doesn't utilize those skills.
Now if we are looking at a scenario of the WHM being a dumbo and just spam cures when its not needed, then you need to communicate with that player and give advice.
