It seems jobs will be a sort of specialization, which i dont necessarilly have a problem with, but in that case every class needs way more than 1 to 1, for their current plans of jobs to pan out, they need like 3 times as many jobs. Otherwise they are killing many different setups, and boiling it down to essentially 7 different setups.

they will also be tying certain set ups to one job.

while i recognize they said they may add some new jobs for each class later, thats a big maybe, and a long time later. until then, it means you will only really have 7 setups/playstyles for any group content. Imagine ffxi with only 7 jobs
at start FFXI had warrior,monk,white mage, black mage, red mage and thief. That's 6 XD btw it's already confirmed they'll add cross-class jobs, just not now
