[MENTION=16430]PvpTay[/MENTION] You could throw me on the list of active ret paladins. Also some other gear options:
Tumultuous Cloak of the Battle gives 6 strength after scaling, the most strength you can get on a cloak (2 more than Soldier).
Mutant Scale Breasplate gives the most strength you can get on a Chest Item.
Merchant Marine Pauldrons give 7 strength after Scaling, making it a great Alliance Only Pre-BOA. That's the same amount of strength you get from Polished Spaulders of Valor.
Also I've gotten frequent +1 strength to wrist enchant recipes to drop from Deadmines and SFK.
+20 Mana is Best in Slot Enchant for Ret because of our small mana pool. Because of our 6% per 2 mana regen we get from Sword of Light, it not only increases our mana pool and our mana regen, as the more mana you have the more you recover. This is important because Ret's only form of viable sustain is from Flash of Light, since we need Holy Power to sustain DPS. Holy power takes so long to build that word of glory isn't even a viable source of sustain and we're better off trying to throw off a Flash of Light, unless you're at <=25% health.
