The problem with a lot of new players is a safety issue, poor to non-existent muzzle control, basic weapons handling. These are things that need to be impressed upon the new arrivals to the community, and that the community as a whole will not brook any kind of unsafe or stupid behavior. The team I play on trains all members to the same standard. With practice and patience, even someone who never picked up a super soaker can be as proficient as someone who served for years in the combat arms.
I've seen the value of training, both in the CF and in the sport, so maybe we as a whole should stress training these"dumb kids" to unlearn bad habits, and to make good shooters out of them
That's my 2 cents
