DPS queues have always been at least 20 mins even before HW on my server, average was 30 mins I'd say. The lower level content is probably a bit quiet for now as people are working on leveling their main job through the quests and story. Personally, with FC exp buff, rested buff and food buff on all the time I have never ran out of quests to level with so not needed to do any dungeons. (Just done the new ones for story so far.) When I level my other jobs I'll probably be back in roulettes.
