You can see in this thread, that many people dont understand the word "statistic" and think that for sure, for sure other client users are different.

Statistics don't mean as much when you isolate them for one specific period.
You can go back and look at iyrnthota's comment 2 pages back to see the stats show FFXIV had a better retention % compared to previous expansions (as long as his numbers are right. I didn't fact check it myself)
