Bumping this again.
Downed Laxasia last night (7th attempt), that was an amazing fight, though some of the effects made it difficult to discern what the heck she was doing. I don't know if I'm overlevelled, but the last few boss fights have felt a lot easier than King of Puppets or the Swamp Monster (downed BRB2 and Corrupted Parade Master first time).
I've gone from wondering what the hell is this game to thinking it may be my personal favourite of the year. The story is pretty cool, some of the characters are brilliant, and the humanity system is quite a nice touch. Few gripes, such as the massive amount of ambush attacks (wears thin after a while), and some sections feel a little long (I don't think chapter 11 needs to be this big).
I've seen quite a few complaints about the parry window but I've found it is pretty manageable, yeah I can't do them flawlessly through a fight but in the Laxasia fight I surprised myself by pulling out some life-saving perfect guards on instinct.
Oh, and the Puppet Ripper is life.
