I used to teach people Raids. There are two reasons why I stopped. First, time constraints. I work afternoons into the evenings on weekdays. Severely limiting my playtime. I would like to feel that I'm making progress towards something when I'm playing. Yes, Raid are very much worth doing. But throw in having to explain every encounter, a few runs to reinforce what's going on, and the actual run where the encounter is completed, and each encounter can easily take over an hour to do. Next, people not owning up to messing up. This is something a lot of people do, but it seems to be more common with people who aren't familiar with the Raid. It happens so often, and it makes me mad every time. Before starting an encounter, we ask if everyone knows what's going on, everyone says yes, we start, something happens that causes a wipe, we ask what happened and who did it so we can try to stop it from happening again, and no one owns up to it. So what happens next? Everyone starts blindly accusing others, people get upset and start arguing back, everyone's too busy trying to prove that they got the biggest pair in the Fireteam to even pay attention to the encounter, leading to countless wipes, more yelling, and eventually everyone rage quitting. It's a video game. It's meant to relieve stress from your daily life, not cause more.
