Spell speed has such a minor effect in this game that PoM will never be useful. You literally have to spam spells to get any worth out of it, and if you're spamming cures you've got bigger problems than how to use PoM effectively.

IMO, they should just replace it with a skill I might actually get some use out of. How about an AoE version of Esuna, or a skill similar to Benediction but removing all debuffs on target rather than healing? There are literally dozens of ways they could give us an actual useful skill, but PoM will always be a waste of a good slot on my toolbar. If you have to use it, you've already failed as a healer.
