I think there is a lot of truth to both sides of this debate. WAR is probably the most utilitarian job right now. The fact that it can take on two roles in a party makes it more beneficial than other jobs. WAR may not out DD a good MNK or a good DRG, but the difference is not huge. WAR can tank better than a MNK and DRG just doesn't have the necessary abilities to tank in any realistic capacity. WAR tanks better than the actual designed tank job, PLD. It's not a surprise that parties learning new raids, pick-up groups, or those who simply want the fastest, easiest, simplest combination of jobs would want WARs before MNK or DRGs.

That being said, it is completely possible to complete the new content with any combination of jobs that meet the basic needs of a party. It's finding people who are willing to run the new content with that combination that is the challenge for most players. Even in fairly close knit LS's, you still hear people's job preferences being pushed aside for jobs that make things easier or more efficient. Chances are unless you play with a set group of close friends, you are probably going to be asked to play a job that isn't your preference unless your job of preference is currently WAR, WHM, BLM, or BRD. Not saying that's right, but it's the reality. It's the player base who has created that mentality with the help of SE's pitiful ability to create balanced content.

To me, that's where the problem lies. SE should be creating content that requires the use of multiple jobs to complete. In my opinion, you should never be able to throw a tank, a healer, and 6 BLMS at something and it becomes 500% easier than it would be with a balanced party. Maybe I'm wrong, but I seem to remember Yoshi-P stating that he felt that party roles fell into 4 categories and those categories are what should comprise a party...a tank, a healer, a DD, and a buffer. If content were balanced, you should be able to run content with a tank, a healer, a DD, a buffer and 4 other party members of mixed abilities. Instead we've seen a tank, a healer, a buffer and 5 BLMs, or a tank, a healer, a buffer and 5 LNCs, or substitute 5 LNCs with 5 ARCs.

I'm not saying content should be easier, but surely there's a way to balance it so that each and every job can offer something to any content whether it be raids or primals. Surely, there's a way to balance things so that PLD, WHM, BLM, BRD, MNK, DRG, WAR, WHM works just as efficiently as WAR, WAR, WHM, WHM, BRD, BLM, BLM, BLM.
