The great thing about Final Fantasy 14 is that due to the nature of how its combat system is setup, it doesn't take a very long time to gather the relevant information to determine whether or not a specific setup is stat capped or performs better. This information can be quickly taken and inputted into a variety of known scenarios within the game (due to a low amount of variance between encounter to encounter) and determined which would be better.

The great thing about Critical Hit Attack Power and 2.0 is that in the past, SE has addressed this stats uselessness in end game scenarios (due to dLvl) and made it more powerful. This is a precedent they have set and attempted to counter/correct. Come 2.0, I see no reason for Critical Hit Attack Power to lose its usefulness. At any rate, from what we have seen, stat caps for all weapons appear to be moving to a lower number than they are currently. This change would further decrease any bonus the Corselet provides outside of accuracy.

Personal attacks and suspension of disbelief won't really provide a strong argument for you.
