All I've read so far is "*insert class/job here* needs to be nerfed because it makes my/this class irrelevant in so and so setting! There for *insert class/job here* needs to be tweaked and nerfed!" When in reality, before Stormblood even came out, we could see the changes classes and skills even before release.

Rather than doing the about face and nerfing a class that's meant to do certain things, they need to revise and relook at each class where there IS a problem and tweak them rather than nerfing said classes due to certain aspects of a class. Offering more constructive suggestions rather than debating into the ground why a class should be nerfed, try to provide solid feedback, backed with actual data.
