Just finished getting to 70 and found that during intense combat (the final trial), I don't have time to bother with gimmicks like Benison and PI. If I do anything, I may macro them into some of my heals but other than that, I don't use them. I just don't have the time to play with them, I am too busy either doing heals or DPS to bother with how many stacks I have on a particular person or on trying to get faster cool downs by inefficient healing. Is WHM good? Yes, I believe it does a good job at healing and is very competent at it. But right now, the new stuff besides upgraded stone and thin air all feel like a "/shrug we don't really know what to give them without making them OP".
