The OP is clearly trolling as we have better ways to acquire some insights about FFXIV population...and isn't declining. However, interestingly, for a game with appeal for the casual population, our clears in extremes/savage/ultimates are pretty high. Look for "achievements" session in ffxivcollect . com.
Unfortunately for some, FFXIV is almost a perfect online experience...just lack some rewards here and there and meaningful open world content.
