Here's my two cents:

Monk has three abilities that can stun a mob, (shoulder tackle, pounce and haymaker) meaning that if you are smart with how you use them, a monk can potentially stun-lock a mob for short periods. You also gain access to abilities that increase your dps, increase your damage resistance, and reduce the recast on your weaponskills. You can literally unleash combos faster than any other job as long as you have the TP. (since mnk can use cross class abilities from lancer, notably invigorate, TP gain isn't that big of a problem.)

On the other hand, Dragoon AF has a huge amount of -enmity, so they can just go crazy on mobs with little fear of gaining hate. They also have the highest TP gain of any job, and if they miss, they have two ws that cost almost nothing to use, are almost guaranteed to hit, and one of them has a pretty useful combo with disembowel.

By comparison, Warrior can deal all kinds of critical damage, and have high hate generation for tanking/crowd control. However they have slow TP gain, aren't quite as accurate, and have slower dps when compared to mnk and drg
