RDM is also derp to play and is very efficient. The issue people have is with its fairly high DPS ceiling coupled with its ease of use and flexibility means that it can achieve higher DPS that classes that have higher ceilings. The reason that BRD has a low ceiling apart from utility is its efficiency which is why BRD has always preformed well in fights since its conception. RDM is as flexible as BRD pretty much but does like 15% more damage. For example: (These are extremely rough approximations but they can work as a visual aid)

Lets say - (Generic fight with mechanics and shit)

BRD DPS: 3800, efficiency: 95%, effective DPS: 3610
DRG DPS: 4050, Efficiency: 85%, effective DPS: 3443
SMN DPS: 4400, Efficiency: 80%, effective DPS: 3520
SAM DPS: 4650, Efficiency: 92%, effective DPS: 4278
RDM DPS: 4400, Efficiency: 95%, effective DPS: 4180

These are pretty much asspull numbers however this highlights why certain DPS preform so well. This isn't factoring utility or lack thereof so you start to see why classes like RDM are targeted by the community nerf bat.

I don't really care about the other classes, I just want to see MCH, DRG, SMN and BLM get addressed but example graph just shows why these new classes are seen as too good (easy to play, not affected by mechanics, high dps ceiling)
