As a raiding retribution paladin i'm really looking forward to 2.3 and the upgraded DPS it brings for me!
I wondered if you could take a look at my gear and tell me what you thinked about it, and what i could do to improve! Obvious upgrades for my are t4 shoulders and legs, and i'm only 5 nethers away from upgrading my chest armour as well.
Being one of the only ret-raiders in my server (that i know of) i've been finding it hard to gain acceptance from my peers who just whisper about me behind my back (retnoob etc) so i'm just wanting to be accepted by being able to do more dps!
You will need to change your talents once 2.3 comes out. I would suggest taking some points from Benediction and finishing off Fanaticism and Improved Blessing of Might (Build). Also, if you don't need Blessing of Kings, you could take 3 points from Protection and put them in the new Pursuit of Justice (Build - the last point goes in Pursuit of Justice). I'm a fan of speed increases as less time running equals more time DPSing. If you need to keep BoK for raiding, consider putting the Cat's Grace enchant on your boots.
On gems and enchants, I think you are putting a little too much weight on critical strike rating/agility, and not enough on Strength. Your crit rating is nice and high, but your AP is a bit low. Also, always go for Strength instead of pure Attack Power, because you get bonuses from Divine Strength and Blessing of Kings.
As well, once 2.3 comes out you're going to need some more hit rating, and you'll get 4% extra crit from talents and racials. Not to mention that Vengeance will last twice as long, so you can keep it up with a lower crit rating.
I would go:
Red slots = Bold Living Ruby (+8 Str)
Yellow slots = Rigid Dawnstone (+8 Hit) until you have 95 hit rating, then Inscribed Noble Topaz (+4 Str/+4 Crit)
Blue slots = Sovereign Nightseye (+4 Str/+6 Sta)
Meta = the one you have is good, but you might also want to consider Relentless Earthstorm Diamond (+12 Agi/+3% critical damage)
As for enchants, you look pretty good. Put a +6 all stats on your chest. If you can squeeze out an extra +16 hit rating (maybe from gems), consider using the Lower City head enchant. It will give you a little more AP and some more mana.
To be honest, you look pretty solid already. You just need to tweak things when 2.3 hits, and I personally would place more emphasis on Strength over crit rating when gemming.
Also, and I'm just throwing this out as an option, if you switched from armorsmithing to weaponsmithing, you would get access to some really nice weapons. But that's a big change, and you do have a decent weapon in Hammer of the Naaru, and you may not have a backup chestpiece.
Any other advice readers--especially Retribution Paladins--would give Firelight?
