IMHO Monk got gutted in Stormblood. I don't know how others felt about 3.0 MNK, but I thought it was perfect. MNK finally had gotten a cool AoE attack, strong burst, it was faster than ever, basically it was a direct improvement over 2.0 MNK. In SB they took a lot of cool mechanics away, made it slower, easier, and RNG based. The new weapon skills are laughable and incredibly underwhelming IMO, it's just extremely lame right now. I'd call it MNK v2.5 instead of 4.0 if I could, it really doesn't feel like an evolution but a step back.
