I queued up for Alliance Roulette as Black Mage and switched to Red Mage to fight a B Mark. The commence timer started almost immediately after I began the fight and I could not finish it in time so I got thrown out of queue and now I have to wait another 30 minutes.

This is not only pointless but frustrating to boot. Not everyone who misses queue is afk or is purposely ignoring it. 45 seconds is not enough time, it should be at least 60 seconds.
