I sort of wish players could only choose one job.

I'm not sure if being limited to one class would solve that. Probably it would just mean that if you are not the desired job, you get left out completely and just sit in town waiting for something to do.

It wouldn't solve it completely, you are right, but it there would content creators would probably be way more inclined to create job balance, so jobs would not get excluded, and the general population would probably try out different combinations for the sheer fact that it would be way harder to put together the "ideal" setup. Again, I support having multiple jobs, but it does create a situation where people will be more inclined to go with the ideal route because it is a lot easier to put together the ideal setup when everyone has every job leveled. Not that doing something with the route of least resistance is bad or anything, it's just that if you want to play a particular job, and it doesn't fit in line with that mentality, tough luck. Hopefully I'm explaining myself well enough, lack of sleep, brain dieing~.

Whenever SE released videos to show us new raids, their party set up included every class/job (plus one additional to make a full party of 8).

I really believe they test new content with mixed parties to make sure it can be done without class stacking, before they release it.

Class stacking is just a natural community pattern based on the human tendency to want to do things easily, quickly and efficiently.

Not everyone follows the prescribed party set ups. Our LS never did the Garuda BLM burn and we really struggled with that fight for a while. But in the end we could beat it with several different set ups, often with the only duplicate job being 2 Bards.

And yeah, a small part of me kind of wishes that you can only level one job. It would make people focus on being great at one thing rather than picking up a job and dropping it like one would with gum. But in the end, what's at fault isn't the system. It's not the system that made people treat jobs this way, it's the way we play and the way people treat the game.

I guess it depends on who you play with.

Most of the people I know excel in 1, 2 or maybe 3 jobs, even if they have everything leveled to 50... so I think specialization still happens even when you can play all jobs on a single character.
