The other obvious problem is the fact that the various tests are wildly imbalanced in terms of the amount of work that's necessary, but they still result in the same rewards. Some tests require full weeks of work to prepare and that effort still doesn't guarantee a pass. In contrast, some of the other tests seem to be virtual gimmes. This was best illustrated when I was running through Seven Lakes last week and someone posted to the regional chat looking for "someone of the female persuasion to introduce himself to for the Test of Marriage principles." I hadn't started the test yet, so I asked what he meant...
"In order to pass principles, you have to 'introduce' yourself to a potential mate."
"Alright, just so I'm clear on this, you gain a level for the equivalent of going up to someone in a bar and saying, How you doin'?"
"I'm not even sure that it's that complicated."
