A lot of sets in WoW continue to get flashier and flashier. The Stormwind Armor is a nice simple base set for a Knight of the Silver Hand/WC 3 Paladin, but the abs and the helmet are a no-go. I used my Tabard of the Lightbringer to cover the abs, and removed the helmet. The Knight's Cloak is a color-working cloak, though I found Frost Leather Cloak works as a great subs for a "leather" look to match the leather belt appearance.
Real Paladins don't need flash and glamor; the Light comes from the heart of the hero, not the armor they wear. If this was good enough for Uther, it's good enough for any of us.
I am a huge fan of Paladin lore and have always played one, and it's nice to have a high-res but simple set to use so we don't have to rely on gear that's 10 years old and shows it's age against our models.
Old Dwarven Hammer is a possible weapon sub for a different hammer, while Destiny is a great sword choice, but many simpler sword models work too. For Holy (Prot as well, but I run Ret/Holy), the Mass of McGowan/Azuresong Mageblade and the Aegis of Stormwind are my choice mogs. I use the Striking Enchant Illusion or the Hidden Enchant Illusion, to either make the enchants more of a subtle "holy aura" or not there at all. I would suggest Crusader Enchant Illusion but for some reason it's asymmetric on the 2-hander hammer models and appears to flow out of the end that hits the enemy, giving an odd appearance, though it works great on other weapon types.
