Been playing with a fun, if somewhat effective Fire based build for my Crusader. I am not sure it's the best thing going but it is interesting to play. I have been completing T6 rifts up to the RG in approx 10 minutes with this. Crusader is slow at killing the RG on T6 so it takes me a couple of minutes to finish the job after that.
Requires:
6 pc Akkhans set (5 with RRoG).
Blade of Prophecy
Around 40% CDR if you can get that high, closer to 50% is better but lose a lot of stats.
As much +Fire % as you can get, Amulet, Cindercoat with RRoG is nice, Bracers (with these 3 you can get up to 60% + fire). I also am using a Lidless Wall with some Fire %.
Nice to haves:
Unity ring. Without it may not be able to do T6 that effectively.
Maximus can replace BoP but it's not as good for Condemn.
Build:
Blessed Hammer - Burning Wrath
Steed Charge - Nightmare
Falling Sword - Superheated
Akarat's Champion - Fire Starter
Condemn - Reciprocate
Bombardment - Annihilate
Passives:
Heavenly Strength
Blunt
Indestructible
Finery
Video of this in action below on Torment 6, on the right elite packs, even on T6 this can take a whole chunk of their HP. You also get pretty good manoeuvrability with the Steed Charge and Falling Sword.

I did not have Harrington buff here, as you can imagine with that up and the same skills you can do a lot of damage in a very short space of time
Rotation of skills is pretty much start with Akarat's, then hit Condemn, Bombardment, and Falling Sword last. Finally run about with the horse for a bit of extra fire damage on the ground, collect any health globes with it too
Hammer is the only spender, so I just use that to clear up whatever is left, I have no problems with no generator with so much Akarat's uptime that Akkhans provides.
Note: I am using Unity with my follower, I can (and have) killed everything in a T6 rift except for the boss using my SoJ instead, but obviously Unity makes it easier!

I will try and record an entire rift start to end with it...
