If you're waiting for 40 minutes for something to pop and you accidentlaly declined something and got hit by a 30 seconds lockout, the 30 second lockout isn't what's going to bother you. It's the fact that you're now going back to queue for probably another 40 minutes before it pops. The only class that has instant pops would be the tank, and honestly, there just aren't that many groups at 2/3 where the tank mysteriously had to go, and given AK/WP pretty much have no dependence on the tank whatsoever in the final boss, there's actually a pretty good chance that such a group is really bad. I think I've seen exactly once where a tank had to go at 2/3 in WP in all the times I've done it. It just doesn't happen very often. Even for the tank class, you could end up waiting for a rather long time to get that spot. Apparently people have no time to play this game but can easily take 20+ minutes trying to find a 2/3 progress wait spamming joins. It doesn't even really help you because you're not the only lazy guy out there who has suddenly figured this out, and it only works if you're a tank to begin with. If you tried that as a DPS it's pretty much always another 40 minutes wait in the queue.
