This is a very good point and perhaps stems from the same issue. I've seen several instances (especially in CM) where new players are never advised on how to deal with a boss, approach a set of mobs, use a specific function (such as cannons), or simply left behind to fend for themselves. Lack of aid and a self-entitled mentality seem to also be more likely than rude players.

I think I'll add this point to the OP, if you don't mind.
