If you're not going to post any constructive information, or add any content to the thread whatsoever, then why bother posting?
That is content.
Its a "dead issue."
It explains why the thread is moot. A dead issue is when Blizzard is familiar with a suggestion, but is not doing it at this time.
Repeat suggestions on the issue are moot. Agreeing in threads about the issue is moot. They already know that thousands of people, at the very least, want this feature. That makes it a dead issue.
"Dead Issue", is a succinct way of commenting on the issue. This is because it is a "dead issue."
Its content, because it is ALL that needs to be said; More information is moot.
This is a less succinct version of that post, which basically says the same thing.
The issue is a longtime known suggestion, dead issue.
It was a dead issue in a previous expansion, when earlier expansion items were still on the cooldown with then "new" items. Blizzard is totally aware when they do this, its not something that they forgot about.
Over time, Blizzard may remove some items from sharing the same cooldown. They have removed items from being on that cooldown in the past. They don't remove them because people continually post threads about it, they remove them when they feel its time to remove them.
"Dead Issue", sums up the issue.
