I love love LOVE the dice rolling. That is a SICK and unique idea. The mechanics are clear. My main concern comes with how much martyring you'll be doing compared to recruiting. I wish I could see the full dice layout, I wish I knew which side had 2 of them on the dice, or if the sixth side is blank. They seem to have a high board presence and seem to be good at policing, and I love the tradeoff of taking extra hits and giving them away from temples, but battles being more tame on temples. The other main problem is trouble policing them. If you have only a couple of warriors on a clearing with a temple, all except the most militant factions will struggle to kill the temple, removing your scoring potential, but it seems pretty easy to rebuild that temple next turn and regain the scoring. Once you get 5 or more temples, your scoring is nearly unstoppable, which forces others to counterplay you when you are still setting up, with few martyrs. Fanatical will allow the Order to keep policing others (without the obvious policing of building a temple right where they already are), without needing to have too much commitment.
Overall, unique ideas and seems fairly balanced, depending on other factions that are being played. The only reason they won't be completely OP is because even with 7 temples, they only get 5 vp, which is an unrealistic number of temples to start.
