Think about it this way. I am farming for a zodiac item. I want to get in as quickly as possible to one of the dungeons. If I queue up as a healer/tank/dps for those dungeons. I won't be competing for a tank spot with another tank that may already be in the queue. Only roulettes will tell you what is in demand and that is not even a guarantee. Trials say Tanks are needed but I queue faster as a dps. The whole system is unreliable on what is the fastest to get in.
From the people I play with, they have a preference but if they are just looking to get in then they will go as any class. Seeing how I have leveled every class but nin, I will go on any of them. But right now the game is forcing me to have a preference. Personally I don't want to be a blm with a bunch of other blm's when there is no melee.
While it won't benefit people who only have a role leveled it will benefit those with multiple roles.
Also how can you be looking for more than a clear. A clear means loot drops, etc. Sands, oils, UATs, etc drop equally for all roles/jobs. Yeah you get loot specific people but not every player is one of those.
Obviously this whole debate is a matter of pessimism and optimism. You are the pessimist that believes that no change to queue times will actually occur. I am the optimist that believes things can improve.
