I'm happy with 90% of the changes we Priests are enjoying in Holy Spec.
Chakra/Holy Words are fun and useful (though macroing my mouseovers for Holy Word is still gonna be a b*tch), Spirit of Redemption with the glyph is great for those fights you're on the edge winning, and Lightwells are much, much more viable now that they're click-and-forget as they should be.
But... Surge of Light either needs to proc more often, or proc off more spells at its current rate. :_; 6% off either our slowish spamheal or our situational DPS for a two-spell exclusive clearcasting proc just isn't right. x.x
