So you're telling me..

samurai > dragoon = ninja > black mage > monk > reaper > summoner > red mage > machinist > bard > dancer
makes more sense to me after monk and reaper pay some of their utility cost

dragoon is the melee with the most support damage buffs and trick attack is the still the biggest damage increase in the game. There's a reason why the devs keep ninja as the weakest melee.

Even if you argue reaper's arcane circle is on par with battle litany, dragoon can still partner up with somebody else to increase their damage by 5%. It's like a weaker dance partner since it's not permanent but still provides a good boost..
Trick attack is a 5% damage increase to the entire party (regardless how far apart they are) with a much better uptime than arcane circle.
