In threads like this, it's easy to lose the context of the conversation. I admit I might have lost that context. But, for clarity, here's the context in which I'm making my comments:
* We're talking about the relative value of racial ASIs in different ability scores and how floating ASIs in TCoE might affect balance. So, when I say that DEX is not objectively better than INT (or any other stat), I mean, specifically, that a racial DEX ASI is not inherently better than one in INT. It depends on character and the way that character is played. I also mean that it is not universally the case that it's better to have a higher DEX than INT.
* You made a list of the ways in which DEX was better than INT, and you stated that none of the advantages that you enumerated were small factors. I said, and I maintain, that for some characters, some of those advantages are small, and some of them are non-factors all together. You simply over-stated your case.
