I was visiting Big Bear Butt's blog (I'll call it B4) and was suprised to hear, the "Additional instances cannot be launched" issue is still prevalent.
When I took my break (was it a month ago?) this was happening. I had a group ready to help me finish a partially cleared instance we "humped" (this seems to be the common phrase across servers) the instance entry for at least 30 minutes trying to get in. I joined a group doing a re-visit to Hyjal, we couldn't get in for a while but we finally did. And me and a friend were duoing some 5-mans and couldn't get in. And once I was farming sanguine hibiscus and couldn't get in.
I consider it another nail, not that I need anymroe, if after a month or so, you still can't do older instances. And, according to B4, perhaps that's how its supposed to be, they are herding us to the wrath instances. He even noted he couldn't get in Stockades easily.
I think that's unacceptable. One of the joys, at least for me, was being able to take my relatively decked out main and finish up old stuff I didn't have time or support to do with a group.
Just like B4 I take it as a given to be able to enter an instance anytime I want. I scoff at the people that complain about the weekly server downtime. Because I understand maintenance is necessary. However, when the server *is* up I should be able to partake in the activities Blizzard has set before us. I consider it a basic necessity.
