Just as Addicted said "Anecdotal evidence doesn't apply to everyone", you say im lucky, I would say you are just unlucky. Remember that I also said that the loot in this game is non-rewarding because you dont NEED it and almost everyone has the same stuff? So calling me lucky would be calling lucky most of the players.
I still believe the drop rates are fine, everytime I run Ifrit/Moogle there usually is a weapon drop, its actually rare to see a run were noone in the group gets a single drop. And not only that, but you can do the same boss plenty of times per day. Compared to those bosses that have a 4 days re-spawn and with a 50% chance of dropping nothing (yep, talking about other games).
This is kind of like when the game started, everyone complained about the experience being to low. SE unfortunately decided to listen to its capricious players and now I see too many people complaining about unable to find low level experience parties. The same will happen if the drop rates are increased, since no one will need the items anymore then there wont be any parties for it.
My only suggestion for you is get a group of friends that are willing to go together on all dungeons, and I can assure you that your bad luck will end.
