Blizzard could do this in week.
Ah, the Holy Priest. Overall my favorite spec. “Why?” you ask? Well it’s simple, I love Holy Fire. Whether I’m fighting a world boss or searing foes with Light, I believe I am a DPS… that has too heal or he will get yelled at. That has not happened yet because Holy Words are strong (except Chastise), Circle of Healing, free Flash Heals from Surge of Light procs AND the three big cooldowns help keep my friends alive at the expense of my damage.
If Blizzard were to remove the “Renewed Faith” or “Afterlife” talents, either one because nobody uses them, we could have a new talent that removes many healing abilities and changes your role to DPS instead. (Most likely “Afterlife” as “Renewed Faith” pairs with “Benediction” and paired talents are good game design. The level thirty talent row is a better place because “Cosmic Ripple” and “Guardian Spirit” are there and it would be a dead row for this playstyle.)
Abilities removed: Holy Word: Serenity, Renew, Heal, Guardian Spirit, Prayer of Healing, Mass Resurrection, Circle of Healing, Holy Word: Sanctify, Divine Hymn, Symbol of Hope, and Shadow Word: Pain.
Abilities gained: Sacred Flame, Holy Word: Cremation, and Silence.
Luminosity Priest
Mastery: Serendipity- Smite has a X% chance to reset the cooldown of Holy Fire. (This is based on an old spell function between the two.)
Holy Word: Cremation- 120 second cooldown, 40 yard range. Causes up to 5 enemies to suffer, dealing X Holy damage over 14 seconds at the target location within 10 yds. (Holy Words: When you cast Holy Fire, the remaining cooldown on Holy Word: Cremation is reduced by 10 sec.)
Sacred Flame- Deals X Holy damage and X Holy damage over 16 seconds. (Literal re-skin of Shadow Word: Pain that deals Holy damage.)
Silence- Brought over to further reflect the nature of a DPS.
Maybe Abilities: Heavenly Tempest, Solar Flare
Heavenly Tempest- 2 second cast time (lowered by haste), 20 second cooldown, 40 yard range. Storm of Light and flame that deals X Holy damage over 8 sec to up to 6 targets in the targeted area within 10 yards. (The main AOE should come from the mastery allowing for more frequent uses of Holy Word: Cremation thanks to Holy Fire resets.)
Solar Flare: 45 second cooldown, 20 yard range. Blind up to 5 targets in front of you, causing their attacks and spells to miss. Last for 3 seconds. (Having unique utility is good, as opposed to classes sharing everything.)
“What about talents? PvP Talents?” Golly gosh, ain’t that a pickle. The talents really don’t need to change even if that is something I would want. Either some talents will be dead or you would have one option. Holy Word: Salvation would need to be unpickable to due how huge it is, even though it has a twelve minute cooldown. PvP talents are diverse enough with some being dead but I have my own opinion on PvP even being in WoW in that it should be its own game for it and PvE’s health.
