The queue times on Balmung are pretty quick. I usually go tank or healer for dungeons, but if I queue expert roulette as a dps, its about 5 mins. At most it will be 10 but that's rare. Syrcus tower and WoD are practically instant queue for dps. LotA is a bit longer since it requires more tanks.

Honestly though it sounds like to me that you just need to take a break if you are not having fun with this game. After all, the reason why we play games is to enjoy them.
