I have been playing for over a year now, and always loved the unique look of Religion armor sets. I personally find it a bit boring that these armor sets have no real stats, or improved version once you hit a fully upgraded (T3) shrine.
I believe that once you have a T3 Shrine+Arch-Priest you can craft Flawless Epic variations of Religion Armor Sets.
List of Improved Religion Armor Sets

Derketo: Medium, Grit, Heat
Yog: Light, Agility, Heat
Set: Medium, Vitality, Heat
Mitra: Light, Vitality, Heat

Future DLC Content Idea
I think there should be a Western Civilization DLC pack brought to Conan Exiles featuring Templar/Crusader Armor Set, and a litany of new weapon skins including a Claymore/Zweihander, Kite Shield, ■■■■■■■ Longsword, Bluesteel Broadsword, Lance. Also including an Artisan bench for Tapestry, Chairs, Pews, and other various decorations.
