FCFS and you! (Updated for 3.3)
With the removal of Seal Twisting in WotLK, Paladins have come to accept the rotation known as FCFS.
FCFS, or First Come First Serve, sounds exactly how it is. With your main attacks (Judgement, CS, DS, Conc, Exorcism and Holy Wrath), you use them in whichever order you please. There are of course, a few rules to this rotation though. Judgement usually always comes first, seeing as the majority of the time it is your most dominant DPS attack. Divine Storm outdamages Crusader Strike when it comes to multiple mobs, and it goes the other way around for single target mobs (mainly thanks to cooldown times, Crusader Strike gets more damage in thanks to being able to attack two and a half times per Divine Storm cooldown assuming no 2P T10).
But don’t get confused by the previous paragraph - finding the best priority is all about having the least amount of clashes in the rotation as possible, rather than having the highest damaging spells come first!
Cooldown management addons might be very useful for Rets who are just starting their career (such as CLCRet). But eventually you’ll learn your favored rotation in almost no time at all. In time, we’ll have detailed graphs showing what to use at what time, so check in regularly at the front page for updates. Remember that if your mana is in a pinch, you can keep up Judgement / Divine Storm / Crusader Strike indefinitely until you get some back.
HoW > CS > Judge > DS > Cons > Exo - Used to be the dominant priority list, but it has quickly grown to other things now that gear is so much better (200/213 to 264 anybody?)
J -> CS -> DS -> HoW -> Cons -> Exo -> HW - Is more of an updated list for your raider roughly in 232 and up gear, aimed directly at Icecrown raiders.
2P T10 and 2P T9 drastically change your priority list. This topic here sheds a fantastic light on what might have been confusing to DPS beginners : “what rotation is right for me?!”
