I've respecced Coriel to Retribution and have been farming ogres in Nagrand for Kurenai and Consortium reputation. Retribution is hilarious, and so much fun. I walk up to an ogre, and it falls over dead. Never gets old.
After playing Ret for a little bit, I'm coming to agree with the idea of only putting 1 point in Improved Judgement. This reduces Judgement to a 9 second cooldown (or 6 Global Cooldowns), which synchronizes well with the Crusader Strike cooldown (6 seconds or 4 GCDs). You essentially end up with the following DPS Cycle:
It's a very similar concept to the Fury Warrior practice of only putting 1 point in Improved Whirlwind and ending up with the same 6/4 GCD cycle with Whirlwind/Bloodthirst.
(As an aside, it's often easier to talk about DPS in terms of Global Cooldowns, rather than using seconds, and mentally converting.)
If you want to macro this for button mashing purposes, it is:
/castsequence Judgement, Seal of Command, Crusader Strike, Crusader Strike, Judgement, Seal of Command, Crusader Strike
Just remember that you need to lead off with an initial Seal.
In any case, I was also looking at Retribution builds, and I'm thinking about how to distribute the last few points. The base build is 5/8/44 with four points left over. At this point, there are three choices, as I see it: Blessing of Kings, 5/5 Improved Blessing of Might, or Pursuit of Justice.
Kings obviously ensures that your raid has Kings. Improved Might gives extra AP to your DPS. However, you don't have Improved Wisdom to go along with it, so I'm not sure how likely it is a raid will put you on Might/Wisdom duty. Pursuit of Justice makes you move significantly faster, and that always helps. Less time moving is more time doing damage, and less time taking damage from the fire.
So a question to the Retribution paladins out there: which of these three options do you prefer?
