Reaper needs additional buffs.

It is quite simple. If the samurai had high personal dps but the rdps was so much lower than its peers then people would not take it. They would take the job with the higher rdps. It HAS to have high ndps AND rdps to compete with the other jobs who bring damage and raid buff+utility.

Raid dps is personal dps combined with raidbuffs (mug littany circle aso are already included) so all jobs should have the same rdps unless they also provide utility. NIN DRG SAM have no utility, while RPR does. Which is why those 3 are slightly ahead.

MNK is an outlier and arguably overtuned.

To put it in other words it doesnt matter if you deal your raid dps through high personal dps like a SAM or mediocre personal dps and raidbuffs like a DRG - both of those should end up with the same raid dps. SAM is justified to have higher personal dps than a DRG but not higher raid dps.

Thats what some people really struggle to understand.
