Personally I think WHM is in a decent place right now. They got the damage they needed after the lily changes so I can't imagine there being many changes now. I'd say the other 3 healers should have priority over it at the moment, and it also needs to be stated that WHM will always be the basic B of healers. Extra DoTs before SCH? Another DPS CD. I personally would not allocate these to WHM before the other jobs are reviewed. And even if the other jobs get them, I wouldn't be surprised if WHM was still kept very basic so that beginner healers aren't overwhelmed.
