@Watachy: WHM was only good in 3.0 because AST was bad. AST offers too much to the raid and WHM offers too little (aka nothing).
Re only reason WHM isn't dead right now is because people are used to the job. It's seriously lacking compared to the other two healers.

Is it a bad healer? No, it isn't. But it pales in comparison to its competition.
Also please tell me what WHMs identity is, if you feel they're not lacking in one.
Please dont say burst heals, pure heals or regen healer because absolutely every other healer does this as well. Please tell me what WHM uniquely brings to the table as a healer.
