"A few minutes" isn't a problem. It's when attempting to get into an instance takes 15, 20 or even more minutes it becomes a problem. You finally get a good group together, you're pumped up, and that door boss rears up and ruins everything.

Anything that isn't a wrath instance is practically impossible to get into, and even the wrath instances will have to bouncing back from the door for a while. I'm glad people are running heroics again, but I'd like to be able to run them at the same time.

This has been going on way longer than the patch has been here, trust me. Blade's Edge has been fixed (hooray!) but we had the instance message issue pop up months ago, so I hardly think it's fair to blame the badges of conquest and casual players.

I agree with you in principle, though. Just understand that people aren't only being shut out for 5 minutes here and there; I had the personal experience of running into that message for in excess of 20 minutes, and I've heard stories of longer wait times. To me, it's unacceptable to have to wait that long to do another time consuming task.

Believe me if it was only a few minutes it would not be a big deal. But on my server it was an enormous issue and a daily topic in trade chat the last 2-3 months. Instances were basically closed down no matter whether it was 10AM, 10PM or 2 AM. You could spend anywhere from 20-30 minutes to hours trying to get into an instance. Most times the groups would fall apart before you could get into the instance. I'll be wildly happy when this is fixed.

I have waited over an hour just to do a heroic that wasn't the daily. It is a big problem.

First of all, this instance launching thing has been going on since well before the patch, so blaming all the casual players is misguided, although I'm sure that didn't help the problem. Why on earth Blizz would implement something that would only encourage dungeon crawling when the system was already broken is the height of stupidity.

Second, it's not just a "few minutes" trying to get into an instance. Try thirty minutes minimum. I have several nights where my group received the "instance cannot be launched" message for an hour to an hour and a half before we finally gave up in disgust. For someone who only has a limited amount of time at night to play, that's an unreasonable amount of time invested in waiting to play. It doesn't seem to matter what time a group tries to get into a dungeon, either: my husband tried to get into MC at 2am and it still refused to launch. Oh wait, that's right, MC is an old-world instance; trying to get into one of those or even BC dungeon is impossible.

I, for one, have never been so happy to see an extended maintenance on Zul'Jin since I started playing 2 years ago.

If it was a few mins wait or a couple of days of it, it would be one thing. But for my server it has been months, during which it has gotten progressively worse. In the mornings its a few minutes and then after 2 or 3 pm its over 30. two nights ago a few guildies and I decided not to give up too quick... 2 hours later, our fingers broken from strafing in and out, we had to give up.
I am very excited for this maintenance and hope desperately that this fixes the issue.

There is a big difference between a few minutes and an hour of door humping for the heroic daily with your guildie buddies
