A person is smart.
A group of people are dumb.
Try this: Start a random vote kick at any time during LFR. 99 times out of 100 it will pass, with every single person having no idea why they pressed yes.
If it's a bad group that is wiping a lot, save yourself the time and stress on trying to educate them and just drop and requeue. You'll be much happier in the end.
