Is there any way to play the game as DPS? Or just end subscription?

Long DPS queues are the case in every single MMO. Doesn't particularly bother me as I just browse the net or do other stuff in-game while waiting. Anyways, MMOs are definitely not for you if you aren't willing to wait in queue. I must say that ex-rulette queue is usually sub 10 minutes, same with WOD and most of the more recent content. This is actually the MMO with the best queue times out of all MMOs I've played.

For leveling purposes you simply do fates/leves while waiting for the queue. Low level content is bound to have longer queues, that's just how it is.

I hear you, I really do, but everyone wanting to play DPS is not something that will change, and is out of SE's control. This is really more of a personal issue that you have. Either join an active FC or get a bunch of friends, or simply quit if it bothers you that much. Such is simply the nature of MMOs, and I think the genre is not for you if you can't handle queue times.
