My fondest memories of Holy Nova trail back to my days in Vanilla. Being boosted in RFC on one of my random characters, a troll priest ploughed the way through with what I remember as the most awesome spell ever, Holy Nova, explosions of light smiting away the smelly troggs that inhabited RFC. And thats when I knew, a priest was to be my main!
Since then, Holy Nova has never really been put to much use, perhaps as a handy way of interrupting flag captures in arathi basin and the likes. But now, it's been side lined further, and is now a glyph choice, it is no longer baseline and it makes me sad.
Honestly though, do many people actually go out of their way to glyph for this? Can they genuinely say it's a good part of their healing in raid environments? Or perhaps it does sick heals in PvP? Im not entirely convinced.
Perhaps with WoD looming, it's time for Holy Nova to have a bit of a revamp? Im all for specc differentiation, and with the new talents for level 100 changing greater heal based on your specc (Clarity of Purpose - Clarity of Will) Holy - Disc, our healing speccs will hopefully feel more differentiated.
My suggestion is, let discipline keep prayer of healing, and instead incorporate Holy Nova as Holy's prayer of healing replacement. Serendipity could work with Holy Nova, increasing the healing done and the range of the explosion, potentially making it a viable form of AoE healing, all the while giving Disc and Holy more seperate and differentiated methods of healing.
I think it could be fun, maybe the implementation of my idea could be tweaked somehow, but it's just a general idea of what could be pretty cool, making this spell Baseline for Holy priests, rather than letting it gather dust as a glyph.
Thats what I think, but what do you guys think?
