If they gave MNK the ability to tank I swear to god I would drop every single class I have right now forever. On the flip side I've got a friend who would love to play PLD as a healer or DPS, plenty of people who would like to play BRD like a Ranger, and DRG as a tank (lol).

As much as I want this though... not counting on it beyond the Deep Dungeons =\
