Positional attacks, indicator is bad.

While you are correct on a technical standpoint, if you want to check your combat log there are external tools like FFlogs or xivanalysis to do that in great detail.

The Floating Combat text has a different purpose, to quickly show information to the player what is happening in that moment, going through the combat log in the game is very tedious.
Also it shouldconvey a feeling of reward for showing a different color when doing the attacks correctly, not punishing for doing it wrong.
