I enjoy M5 and M6. They have no unique mechanics, not really. But they're full of flavor, which disguises it really well. M7 I just find a nightmare to read, for some reason? I find his tells hard to determine quickly enough. M8 is...there? It's the least interesting fight out of the 4 by far, I think. Curious what Savage is going to be like.

The most interesting fight I've seen in Dawntrail so far is probably EX4. The connecting floor tiles is a really cool mechanic.
