Right now that is primarily the attitude in the game.
However, now that a lot of people have gone through, gotten their dark light, and are doing the slow climb to relic/Allagan, the crafted gear is starting to appear more and more often (Like my totally awesome Pink Spank Tank gear).
However, at this time there are no debuff weapons anymore (there were in 1.0, but I believe they were all removed with the exception of the maddening dagger and Fostbite, however, neither of them have a listed effect anymore).
Yoshi made a comment about the possibility of them in the future, however, as of now, that entire aspect of the game has been removed. Add to that, debuff potions are VERY limited in use, everything right now is focused on ability debuffs, not item debuffs.
