A few patches after big bang, skills are changed again.

I still wonder do they still keep this with Final Cut: Passive Effects - Permanently increases damage for Fatal Blow, Slash Storm, Tornado Spin, Bloody Storm, Upper Stab, and Flying Assaulter by 25%. Cant wait for extractions, awwwwwwwwwwww!

With fatal blow being:

fatal blow:
master level: 30; 85% x 8

I highly doubt that the increase by 25% is unchanged because:

phantom blow:
master level: 30; 110% x 6

That would make Fatal blow better than phantom blow, unless phantom blow is incredibly fast and/or has special effects, or is also increased by Final Cut.
