Your entire argument hinges on a simple philosophy: Jobs are all secretly balanced due to "higher quality data" that we are not privy to. If this were true, the developers are idiots for not releasing this information. Why? It destroys the meta. Because until the playerbase has objective,
written, proof, they will always fall back on FFLogs and ACT. No one cares what Yoshida claims. They want numbers that can be cross referenced and properly scrutinized. By your insistence, the developers have this information, but won't release it because... reasons? Furthermore, this inherently makes job changes pointless. Why did Black Mage get a fairly high buff? Why is Samurai slated for one? According to you, there is no meta, thus neither job has any reason to see changes. At least to their damage.
Basically, your stance makes the dev team appear as utter fools who possess the tools to destroy a culture they openly dislike ((FFlogs) yet won't, and make job changes to already balanced jobs because... boredom, I guess?
