Can I progress in storyline without doing dungeons?

If you don't like the long queuing times for a ranged DPS job like BLM, try rolling a melee DPS. Or a healer. Or a tank.

A healer or tank will generally get shorter queues, but the game makes no distinction between ranged DPS and melee DPS. Both are filling the same DPS slots, and both will take just as long in the queue.

This is incorrect regarding queue times. The DF will, if it can, put both a melee and a ranged DPS in your group (or 2 of each in 8 man stuff). As I posted above currently Ranged DPS is in larger supply and generally has much longer wait times than melee DPS and you can test this out yourself just queueing up for dungeons. 2.2 actually changed the "average time" while queued and you get different times shown if you are a melee or a ranged DPS when previously it was averaged between the two.
