Hi! So Holy healing specs at endgame have been discussed at lengths, but I was wondering about the times when you don't heal in a dungeon or raid: 1. Is there any middle of the way spec which allows for decent healing but also some questing on the side and maybe even W-PvP? I don't really want to pay 2 * 50G each time I go to a dungeon or raid 2. In general, how do you grind as holy at 60? Which of the spells do you use (MB, Smite, HF,S:P?) Thanks a lot! Munzi
