However, we should be expecting content that's varied and somewhat challenging. The reason why even semi-casual players are running out of things to do is because of the ubiquitious accessibility of everything that's end-game related.
The OP only stated what Yoshi-P told us, Not what is going to be in 2.1 as a whole.

He is only basing his OP on facts Yoshi-P has said, but what Yoshi-P said isn't all in 2.1.


Also: The game has just came out, there is a lot of things to do in this game. as with all new MMO's ( FFXI, WoW etc) They need time to add new content. Within a years time, there will be this "variety" you and some people want ( end-game wise).

When a MMO just starts out, end-game content will be scarce ( but there is options like Gaurda/Titan/Ifrit Hard mode, and Coil, and Mythos farming) I feel that's more than enough for a game that's starting out.

In a years time, You should see a lot of end-game content. People just need to be a little patient.
