I was merely pointing out the fallacy in your argument since you seem to only be looking at the dps of 1 job as opposed to raid-wide dps, which is what people should be focussed on when raiding. If you want to be arbitrary about it, then I guess it'd go something like this...
Tanks first: WAR is clearly OP and always will be for some reason blah blah so that's in regardless, DRK does more damage than PLD so back to 3.0 style and PLD is out.
DPS: NIN has Trick Attack and Goad, DRG has piercing debuff to help BRD and MCH, so MNK is gone. then we take BRD since MCH has that pesky turret, and BLM as it still has a slightly better single target dps rate. so MCH and SMN are out.
Heals: well AST is too RNG on cards so we'll just stick with SCH and WHM.
There we go, every raid group should now be WAR, DRK, NIN, DRG, BRD, BLM, SCH, WHM because reasons.
