I have no idea what you are even talking about. The point is very simple:
FF14 has a set of content and goals for casual players and a set of content and goals for more hardcore players. Also, apart from the MSQ, very very very little content is contingent on doing some other kind of content. Almost all content is an island. This keeps casual players and hardcore players largely segregated, and it keeps players with different interests separated.
WoW blurs the lines between these things, creating this constant ramp that players are quickly pushed up and strong incentives to branch out into different kinds of content. This causes players of various play styles to get mashed together, especially casual and hardcore players.
This is not really a debatable point. These are brute facts I am presenting.
