From the launch of the game FFXIV has had lot f bugs, and it is true that it lacks lot of content specially end game events, however is it true that there are no other things to do more than crafting like crazy, rank other classes, do leves, and kill same NMs, not at all, there are still other things to do like go to places people usually don't go, research decent places to rank at 50 once cap is raised, and of course fight high challenging monsters, monsters of even rank 90, which are doable, but with a good party strategy, and have that feeling of honor a linkshell and a player must have been able to defeat continuously the most difficult monsters in the game, those high challenge monster haven't been fought too much that there are even some of them with unexplored drops. It is true that there are items dropped that are used for nothing yet, or maybe nobody has found yet what they do, and there is one more thing, have you seen how items such as gold dust worth a lot in markets. The other items that are dropped by non usual fought mobs are going to be pretty expensive soon since they are going to be used for something, quest, maybe in the quest to unlock jobs, there are only few linkshell who understand this, so they farm the items and store them in a bank to be prepared for things to come.
There are places where nobody goes, because monsters are "too hard", such as Soth Bloodshore, TigerHelm, North west section of Coerthas, which also means there are still lots of unexplored drops.
So is it really true that there are no things to do.
I've done some research with a couple of friend and we already know place where to get up to 500sp per mob with easy kills at rank 50, we also got drops that no one seems to care yet, such as non used mob currency, skins dropped from monsters that no one seem to care, so we already have advantages in game for when those things are to be used, and can sell it needed, whereas the linkshells that do not do this, when time comes will have to have a learning curve on how to succesfully fight these monsters and will be having several party wipe experience of committing suicide to kill mobs, instead of playing like a pro.
One more thing is when raids come, how people expect to be succesfull on raids if they don't know to to fight normal world high rank mobs, since in end game raids usually the mobs are of equal or higher rank than the higher normal mobs in game.
