His damage honestly doesn't seem that different overall. He actually gets less damage on average for each star so he will have to use more of them to deal good damage, hence why he gets meter faster.
As for aggressive versus passive, it has always been like this. Hakumen will get 8 stars, unless you are constantly getting hit by him so he has to speed them in combos. I think you should play the match-up basically the same way as Extend. His corner carry is less ridiculous this time and the time based combo system means you won't be eating 3.5K from a 2A and ending up in the corner. I also don't think Nu has the tools to really play ultra aggressive against Hakumen anyway.
