You are correct. I never solo anything, because this is a team game, and I enjoy having a laugh when I play. But people do use the wrong weapons. Also a solo nightfall requires quite a high skill level and the ability to cover and shoot at the correct times. On another subject, why have you never completed the raid? Your missing out on a decent bit of gameplay. Give you a lot of great weapons for the nightfall. I got vex, gjallarhorn, tlw and hawkmoon in 1 raid this week.
