Why is there still so much to do at end game?

[Altena]

A Realm Reborn has been out for 3 months, FFXIV 1.0 been out for 2.5 yearsish ( then got shut down).

I know some people like to think FFXIV ARR is an expansion of sorts. But where exactly has the game been expanded? Personally it's a new game, and I am treating it as such.

The argument people make is based on character progress/nothing to do because they have finished everything.

While systems and battle mechanics have changed, and basically yes - the whole game... Character data has been carried over.
ie. Players have been progressing their character for 3 years.
There is nothing to do for many of us, because our characters are 2.5 years ahead of the "new" game's life.

Call it new all you like, others will call it 3 years old.
Point is - progression wise, players have been playing for 3 years.
