Hello. I recently returned to the game and I'm being told WHM is a garbage class getting the lowest DPS and healing in the new savages. I'm told any other healer class is better - can anyone shed light on this?

I use to really love WHM but I've been leveling other healers, only because I've been warned WHM is not worth the effort. Is it true? PS, the character listed on the forum is not my main.
