I am stoked for the INT/WIS swap. Gives us a (another?) martial class where you are encouraged to play a smart character and not use INT as a dump stat. For someone who RPs heavily based on mental stats it is really quite boring to always play a dumb fighter or something of that kind and I am really excited to play my next campaign as this updated Blood Hunter. :)
Also, the subclass changes are spot on and I am looking forward to seeing people use them in my future campaigns (both as co-players and while I am DMing).
