I was in the same boat as well, had a 41 Dragoon then switched to my Monk which worked out great since I all already had all the great Dragoon abilities. Dragoon don't have a lot of abilities off GCD just their jumps and their stun for damage. Only 2 jumps actually do good dmg while the others are use at the right time kind of thing. The Dragoon has buffs off GCD but every class does. The good thing about the Monk is they have the lowest GCD once you get a full stack of Greased Lightning which is amazing. I decided on the Monk because you get more options than the Dragoon.
