KMST 1.2.409 - Thief/Pirate Revamp

I wonder if bucs would of been happy if nexon simply copy and paste the monks skills from dfo.

Nah. Monks were also mediocre in that game as well, compared to the facerolls delivered by any class with natural elemental attacks or naturally high critical damage/rates. Strikers are more in line of what your proposed Bucc change needs, with their scary high base damage and naturally high critical hit rate and giving the proverbial middle finger to anything that can damage them or push them back.
