When I wrote "the same", I kinda meant "perfectly balanced". If it doesn't matter if you come DRG, DRK, SAM, WAR, or RNG; why have them be seperate jobs in the first place? Why not have one job named "Damage Dealer"?
I do understand that people have preferences, and that's a good thing.
People need to become realists though, and realize that everything will never be in PERFECT balance, because the jobs are intrinsically different. Because of this, depending on the content certain jobs will shine and others will not. That's the way it should be.

SMN is good in Walk of Echoes. That doesn't mean nerf SMN or buff WoE, it means if you want to do WoE you should level SMN
BST is good in Dynamis. That doesn't mean nerf BST or buff Dynamis, it means if you want to do Dyanmis you should level BST
MNK and WHM are good in Abyssea. That doesn't mean nerf MNK or WHM or buff Abyssea, it means if you want to do Abyssea you should level MNK or WHM

All this whining of one job over the next; just stuff it and wait a few months and things will probably be completely different.
