People have been saying this every single expansion thus far, and every single expansion we get two baby steps forward and two giant leaps backward, with job fixes being largely band-aid updates and needed reworks taking a backseat to Gold Saucer updates and fishing content. Monk mains have never, in the history of the game, had a decently-playable job throughout the story, and we only tend to get the mother of all band-aid patches after all the primary story is all said and done.
So, you can think that all you want, but as the saying goes, "fool me once, shame on you, fool me twice, shame on me,"... except for those of us keeping count, it's more like five or six times now already, so the trust that "next time they'll get it right for sure" is dismally low. This isn't our first rodeo, after all.
I've also come to learn that lots of people who claim to have been MNKs back in 2.0 or 2.1 are full of it, since I've asked them what MNK was like back then, and their answer seems to just be like level-synced MNK in Labyrinth. They don't seem to remember the god-awful primitive and slow combat in 2.x, horrible moves nobody liked such as Featherfoot and Haymaker, how PB was on a 3-minute cooldown in a time when a party wipe wouldn't reset your cooldowns so you had to sit and wait for a few minutes before attempting the next pull, or how you were a White Mage's babysitter because Blunt Resistance Down helped the healers regen MP off of their auto-attacks back when they didn't have better MP management tools and auto-attacks were a more major part of the combat loop as things were that slow and lacking back then. It's just something people claim to bandwagon onto popular sentiments and demand the simplification of MNK since they don't like weaving oGCDs and would rather the job be dumbed down than endure a learning curve.
What's more offensive to me than the state of MNK is a lot of the stuff SURROUNDING the MNK updates and the live letter. From how abruptly the MNK demonstration was cut off to spend absurd amounts of time on Triple Triad, to Yoshi-P admitting he doesn't really know how to play the job, to none of the changes not brought up in the LL being anything of note in spite of us being told there was more, to even the elemental fists being noticeably absent from the patch notes, etc... it feels like they didn't even start working on it until the night before the live letter and then went "screw it" for the remaining stuff they didn't cover. So much for being told that it would be so expensive and take two more months to do, and that they worked hard to maintain the busy feeling of the job, when it feels like it was rushed out in an afternoon at the 11th hour and it's actually LESS busy because we have even fewer buttons to push now.
