Monk and dragoons are both hard. Monks rely on perfect rotation and the duration of each stance or buff only gives the user 1-2 mistakes and dps suffers heavilty.


Summoner - almost every hard skill they have is dot. You have to manage it well as well as the aether buff which lets you use their 300potency skill


Mages - failed rotations usually makes your regen phase longer and dps will suffer.


Bard - simply watch out if a party member needs support then just dps and kite all the way
