I love challenging stuff, I want the game to get harder, but this is not the right time.
Square Enix is trying to get as many players as possible before 2.0 and that is exactly what they should do. Making or adding some hard content that just 5% of the few thousand players can actually do is not a good thing at this stage of the game. There is hardly enough content as it is, making it hard to access is a terrible idea, right now.
When 2.0 hits, FFXIV gets more players, PS3 version is released and the game has enough content might be the right time to add truely challenging/hard content.
I am looking forward to it, but not going to cry, whing or ask for it right now, since it would be a stupid business move.
