It is a fact now that many players now are already geared with Darklight (Philosopher's tome items) and quite a fair amount of i90s (Allagan and Myth tome gears).
Thus if the reward for Hard Mode dungeons is still phil/myth tomes, I do not think that is going to be a strong reason for the players above to play Hard Mode dungeon.

What type of unique reward is planned in the Hard Mode dungeons for players such as above? Will there be a reward such as ADS plating, Ifrit's horn, Garuda's feather, Titan's heart type of ultra rare rewards?
