I tried a few rifts tonight and while I did find a final witness I dont have all I need. But like you said steed charge is mandatory in rifts, you need the mobility as monks are just so fast. I didnt even think of lvling the defensive gems thats a good point. I was attempting toxin, powerful and gogok.
I think the main problem is if you have a good DPS monk/DH or whatever they can blast T6 solo in a 4 man party so having a buff sader is less important. Steed charge helps a bit to get ahead of the monks and kind of pull stuff together but they'd kill that shit really fast either way. GR35+ is where it really starts to shine because the higher HP makes everyone group up more.
My biggest problems so far have been tight areas with arcane beams and pulling too many things to me and getting trapped since I run iron skin in GR. I can survive most of the time but sometimes I trap myself in a really bad spot and not having an escape hurts a lot.
Being able to revive without getting interrupted is amazing.
I've since switched my amulet to a Julia's. I lost 8% CDR but I still have enough to have 100% uptime on my law and the bonus is arcane beams should no longer be a problem. Having 3-4 spawn right on top of you wrecks you even with 70mil toughness haha.
I'm using the regen gem. I didn't have it at 25 but it helped a lot. I got it to 25 finally so we'll see if it makes a huge difference.
I'm curious about the other defensive gem. I have ~1.3mil hp and the other one gives 70% mitigation against non-phys after you drop under 50% so it seems like I'd be nearly invincible reviving people and such especially if I popped the iron skin before starting revive.
I managed to get the support crusader going, all I'm missing to complete the most important part of the build is Final Witness and Illusory Boots, so I'm going to need some kind people's help to farm Act 2 bounties. After that, I need to start doing grifts for gems.

Oh yeah I forgot about krem bracer and illusory boots. Might have to try to get those but I'll have to find a way to get CDR back after I lose my belt to crimson and boots to illusory
