I see no problem with it. I go into a queue, I switch to another job and do something else whilst waiting. Doesn't usually take more than 30 mins to get in a party unless it's during dead hours of the night. But in the end compared to the 8 hours I used to wait in FFXI for playing the same job 30 mins is nothing. Actually it shouldn't even take that long to get in a party in such early stages of the game with more players than the server can handle. This isn't so much about not getting in a dungeon party to complete your class quest in almost instant-invite like a tank or healer, this more about FATEs giving so much xp that people spam those instead of dungeons so there's barely any available players for doing dungeons with.
