I keep seeing disc priests from "top" guilds on my server(even though they're all just bad imo) specced into it and I don't understand why. Tell me when on earth is there time to cast smite when heals need to be tossed. Is this really something I should be speccing into because I can't seem to see it being worth the points. Is it going to be important for cata? I never have mana issues in any fight. Even with rapture being nerfed. Pop shadowfiend with hymn of hope and arcane torrent is enough for me. Heroic LK is a breeze and I still pull 50% of heals with constant bubbling. With that being said why are people actually using this ability!
