Although I've played my priest for 4 years, I played most of the time in various discipline and holy builds. I experimented only a bit with shadow, but that was quite some time ago, and the life of a shadow priest certainly has changed. So when patch 3.1 comes and introduces dual spec, giving me the opportunity to switch to shadow when the raid needs less healing and more dps, I'm woefully unprepared.
Luckily my guild currently has a surplus of healers, so I might have an opportunity to spec to shadow now for a while to practice. But while I found a bunch of different shadow talent builds, I'm not quite sure which talents are essential and which are just nice but fluff. And, more importantly, I have no idea about the spell rotation of a shadow priest in a raid.
Can anyone help me out with a link or advice on what spells shadow priests cast in a raid? The dps method I know for shadow priests, fear kiting a.k.a. face melting, is certainly for soloing only, and not applicable to raiding. So, what debuffs must a shadow priest constantly keep up on a tank and spank boss, and what spells does he cast in between debuffs to deal maximum damage?
