As with the poster above, I play all three classes because I want to fit in where I'm needed. Granted, I run with an FC for the most part (which, to be fair, may also be an option you haven't considered - if you have an FC, you should have a group of people that can help you get into/through dungeons), but even though my main is healer I have dps and a tank all at 70 so that if I'm needed for something else I can fill in a spot (even though, for example, I don't enjoy tanking and am not confident in it).

Do I blame you for not wanting to play something you don't enjoy to queue? No, but on the same hand, everybody else should be able to play whatever they want to queue. Somebody else shouldn't be forced to give up the class they enjoy solely so that you can have a faster queue time.
