Convenience I suppose...
I agree though, a lot more has to be done to encourage new players into the multiplayer community.
Hate to say it, some of this community does come across as elitist in terms of accepting new players who, initially, don't know what they are doing. It took me quite a few attempts to find a flying community that accepts players (skilled or otherwise) who just want to have fun.
Personally I find it a great priviledge to help new players get to grips with the game.
