There are far fewer opportunities to have that "oh, I've been doing things wrong. I should change my playstyle" moment. Between duty support npcs and the terms of service scaring real players from speaking up, it's no wonder that we get people at 90 who don't know what they're doing and make things take way longer than they should. Some of the people playing this game today would have meltdowns if they had to exist in the mmo communities of the mid 2000's, where people would just flame you until you got better or left their group. Not saying we should go back to that, just that it used to be the opposite end of the spectrum.
