So I've been messing around with the crusade stuff, and now I really have to question why they even bothered.
Fights were a lot faster during beta phase 2 at least. Like gargoyles weren't insanely tanky for no real reason. Then again, many of your units weren't very tanky during that phase either. But I think they had the overall balance about right during phase 2, so it's just baffling that it has seemingly regressed in the full release to the level where a bad fight may snowball into a miserable experience for the rest of your playthrough because you aren't given enough time to recover, from what I've observed from other people. All of my fights have ended perfectly thus far, but again, I have the power of foresight.
Please for the love of everything that's holy, just ditch the management stuff for the next game. I understand the impact it adds to the narrative, but it seems like it's just sinking development resources at this point for a concept of dubious value. Just like the origin system.
