I am just hoping they don't add more heals to WHM in SB. That might be odd to say but WHM is already stupid powerful with its heals and at this point any additional healing has a far smaller value. Throughput healing is about effectively meeting a quota on the amount of heals given in any given point at time. Anything on top of that is wasteful and of little value. WHM is also extremely good at meeting that quota. More heals on top of that really don't offer much to a WHM's tool kit.
