FFXIV is never going to follow same path as wow did.
Our game is much more diverse, we have much more interesting content in which devs spend considerable amount of time, distributed even between all activities. This brings diverse difficulties to play for all sorts of players.
Blizzard on the other hand is basically focusing their game around mythic content, making their game w blend of all flavours into a terrible tasting soup. FFxiv feeds ypu different stuff in separate containers.
