When I'm queuing as a dps I usually mark it for join in progress which helps a little but can kinda stink if they're halfway through already. I also go fate farming and/or go after my daily hunts while I'm waiting. Sometimes I'll get the duty to pop real quickly and other times it goes way beyond the estimate. It helps an extreme amount if you can find a tank to queue with you. Sometimes its the time of day or day of the week that plays a factor too. Might be a lot of people off or doing their static runs. Don't give up though.
