I think the AP requirements that some people post for the easiest most dumb dungeons is ridiculous. Regardless, it should be nothing more than a source of a chuckle. Form your own party.
The problem is, people are too lazy and scared to form their own parties. They are followers, they're afraid if they make their own party they will have to be responsible. Last but not least a lot of folks get upset by the AP requirements because they like getting carried and don't want to be left out.
I'm not judging people. We all do it at some time, but this shit is not thread worthy. If you see a 6-man requiring 500+ AP go make your own for 400 AP and it will fill up with a bunch of people quicker than the 500 AP one. Simple.
