Being able to shapeshift your body around attacks is never said to require FS, and what I meant by basic CoO was just the non-advanced form, not some fodder level CoO
We know for a fact that basic CoO lets you predict and evade attacks, so logically, if you're a logia with decent CoO, you could shapeshift around attacks perfectly fine.
If you can show me an Admiral actually knowing what will happen 5-10 seconds into the future with certainty like Katakuri or Luffy do then I'll concede, until then it's just basic prediction and not future sight.
