Complete infernal vitrine before Crusader's shrines?

I'm thinking of getting the Binding Blade DLC soon. I'm more interested in Duelist, but I want to incorporate Crusader into my comps since I've heard great things and I'm paying for him.

However, I'm worried about finishing his questline and the Warlord becoming a roaming boss. I'm working my way through the infernal vitrine and some of the teams I've planned would have trouble with him (ex. Bleed comps). He looks like a tough fellow and I especially don't want to run into him Ordained with a higher spawn chance on Bastard's Beacon.

So how much of a hassle is the Warlord in infernal vitrine runs? Am I overestimating his difficulty?

Is Crusader's full skillset so good for infernal vitrine that it's worth the tradeoff of Warlord spawns? Or should I finish his shrines after doing the flames where my planned team won't be a good match vs the Warlord?

I'm overthinking things and rambling, my apologies but I'm so excited! Thanks in advance!
