I've always loved the concept of a darkmender - and I use this term vaguely, not in reference to a specific class. A class that uses shadow magic to heal their allies. According to Warcraft lore, Shadow Priests are technically darkmenders, but in game, they're primarily damage dealers. There is also some lore that supports Death Knights being darkmenders of sorts (they served the same role as Paladins did for the Scourge campaign) in Warcraft 3. With Rift's Storm Legion expansion releasing soon, with the new Defiler soul for Clerics, my interest in darkmenders has been revitalized. I was just curious how the World of Warcraft community feels about the possibility of a dedicated darkmender style class. Of course, there would have to be at least one damage dealing spec, which is where I see a problem coming in. With Shadow Priests and Warlocks, I don't think there's a whole hell of a lot of room left for another shadow-based caster.
As a long time Shadow Priest myself, I might even support the conversion of the Shadow spec into a more dedicated healing or hybrid spec, like Rift's Chloromancer, or countless other MMOs' blood priests/mages, or something.
Perhaps it could be part of an Old God-themed class. There's also still room for more shadow-based melee classes (ie, Lightslayers - something more Rogue-like as opposed to the Death Knight's Warrior-like style).
Kind of just rambling, but anyone have any thoughts on the subject?
As a side note, I think that Shadow Priest's Glyph of Dark Binding should alter graphics and icons to something more shadow-appropriate, but there's a ton of minor cosmetic things I'd love (for example: Paladin abilities having different names and spell effects depending on your flavor (sun-themed abilities for Tauren)), but meh, it's whatever.
