Add to this they want to give melee a niche. Melee and hunters will shine on movement heavy fights. Priests won't, but we already don't. We just get more people to compete for the bench spot in these situations. Its actually a good thing if we are on the same level of the other casters. Its just that instead of us getting buffed, they get nerfed.
Stuff like Glyph of Penance I cannot imagine staying either. Maybe with 100% more mana cost. Instant Holy Fire? That is a minor thing really, but that dot can proc ToF.
I think its a good thing. If CDs are being combined and provide multiple utility and it makes you think if you want to save the CD I think thats a good thing, too. Inner Focus has 3 utilities in one (reduced mana cost, 100% crit, no silence/interrupt/dispel). Psychic Horror has also 2 (fear + disarm). Fear Ward for example has only 1. You could easily combine Power Infusion with Fear Ward for example except for PI isn't baseline while Fear Ward is.
