I'll have to play the dlc myself to say for sure. But looking up some things i have 3 tiny nitpicks so far:
1) we finally got an old monk style fight that seems like it was executed wonderfully. my worry though is that it's locked behind dlc and arguably one of the toughest fights souls players have seen just to join said covenant. and that boss is optional. I unfortunately don't see myself rushing to get this covenant done on any character aside from my main.
2) The Midir fight looks fantastic. But it does bother me that at the moment killing him via killing through his tail is a little unnerving to me. But at least the ranged attacks don't have BS hitboxes this time around. (from watching anyway.)
3) Despite this being the "city of the hollows" I was sure we'd see more about the sabel church. Even more so considering their involvement in the last dlc (more or less.) and nothing more on velka. Hopefully the lore is heavy with this dlc to make up for those shortcomings.
Overall the 3 things that usually sell me for souls dlc are the weapons/armors, music, and boss fights. The weapons are downright amazing. There is a little something for everyone. armor is a good step up from AoA but that's not really saying much. I was VERY impressed by the sound tracks this time around. Wasn't expecting that. And the boss fights all seem very strong this time as well.
I can't wait to feel out the midir fight and see if it topples my enjoyment of kalameets fight. Gaels fight looks good in it's own right. But I don't think it topples the fight with sir Artorias or Sir alonne. But it deff contends with Knight raimes boss fight. and easily destroys any other humanoid boss fight. I'm on the fence about the demon prince fight. As, at least in my opinion, demon fights in the souls series (disregarding demon souls since i've little experience) have always been weird. often either gimmicky or just frustrating.
And aside from my other complaints about the halflight fight I feel like this is easily the weakest fight if you are someone who plays offline. NPC fights always never seem to reach that level of satisfaction a normal boss gives.
A perfect evening involves pizza, some tea, some bros, and dark souls.
