With patch 2.4 live, lets take a look at what it's offering those of the more Priestly persuasion. Gear, a few talent and spell changes, and some new fun in the new instances will be a boon for your Priest.
For our Shadow brothers, you can now look forward to Fear Ward in Shadowform and a somewhat nerfed Vampiric Touch (they've fixed the bug where casting lower ranks wasn't penalized like other healing spells are).
Disc priest, like Nethaera, can look forward to a slightly buffed Inner Focus (though in reality it's not a very big buff, just Chastise, Starshards, and Shadowguard corrections in that they'll no longer trigger the Inner Focus charge). Reflective Shield will not break CC, and a penalizing effect has been added to lower ranked Power Word: Shield. Chastise is now instant cast, and will no longer dis orient the target. And of course, Power Infusion has been changed.
Holy rollers will like that Silent Resolve now affects a wider range of spells. Mass Dispel will affect 10 targets instead of 5.
There will be several pieces of gear added as well.
