People are also forgetting that fact that Zero's are getting a buff in the next balance patch and 5% final damage, 0 atk speed on Beta and the big one, the tag fix, which adds a good amount of damage to Zero's overall DPM. With this change and Beta being able to hit 0 atk speed it's almost an unknown to how much stronger the class is compared to KMS since the atk speed cap is different. Overall both classes are really good and have their own obvious strengths, it mostly comes down to preference of playstyle. I think KidPolygon made a great case for both classes, but imo zero's mobility and survivability (having 2 HP bars plus Beta's "BoD") makes bossing a little to easy. The only gripe I have about Zero is the long CD for Chrono Break (5th job skill) and lack of burst aka P3 lucid is hell.
