4kk accounts registred is not crazy and it's not daily active accounts. It means they bought the game and registered. Many of them quited, some banned, other stayed. Some people play every day, some play few hours per week and some other pay 2-3 months then they quit and come back again. That's absolutely normal for an mmo. FFXIV proved a huge success. Very few games if none at all ever achieved that. To fully recover after its death and not only that but also turn to huge profit. And the fun just now begins with the expansion. Now we gonna get truly new content for the first time. Expect loads of people in June and July. Anyway I really don't care as long as I see people around. Population always fluctuate.
