Like a lot of people I was pretty upset when the Act 3 battles were turned into dice games. I've changed my mind on them, after giving them a shot instead of hitting auto win I realized they're pretty fun.
The one issue I have is that the battles feel a lot less epic than before. Instead of having to fight through multiple layers of defenses before taking out an area's boss, all the MC has to do is show up and challenge the boss to a 1 on 1. For a city that's supposedly at war, there's not much showing the scale of the fighting.
I think a good way to reintroduce a larger scale to the fights would be to bring back the earlier combat system, while keeping the current system as the final stage before conquering a district. It's an easy way to make conquering districts feel more impactful, like slowly chipping away at an occupying force before taking out the boss in a duel when her forces are depleted.
Still love this game, looking forward to the Lyx update!
