Basically, Warrior/Guardian parties are preferred by puggers because you don’t know your teammates and they’re the classes with the lowest skill floor.
A bad player playing a warrior or guardian still contributes without getting killed every five seconds because his survivability is largely passive and doesn’t require as much player reaction, knowledge, or skill as another class does to achieve the same (or often better) degrees of utility or damage.
By that logic, classes other than warrior or guardian are Rube Goldberg inventions that make the game harder, just to make it harder. Granted, wandering through the world with my guardian takes less effort than with my necro, but in a dungeon, anything goes. If a class takes twice the effort to survive in a dungeon as another, with no real benefit, what’s the point? I’m not saying that is necessarily the case, but that’s what it sounded like you were saying.
