Main reason: They don't want to see their stats fall, which is what would happen if they played people at their skill level. You have to remember, these are people who have never been good at anything in their entire life. They got picked last for kickball at school. Their only significant relationships are with their clanmates and they took their Xbox as a date to prom. They live in their parent's basement despite being in their thirties and currently have 10+ tabs of weird catgirl porn open in Firefox.
