Following up with the 'fast typing in raids' comments, another thing that I really felt was great in EQ was the social skills you had to pickup to progress through the game. ( Apologies if this is has already been talked about 100x here )
Learning to introduce yourself to strangers and form relations... There was only so much room in the world and to get into a group you would have to reach out to people in the zones and ask if you could get in line to join when someone would log, depending on how good you were could possibly mean a few hours of downtime between leveling. Being able to talk to everyone was a game in itself.
I bring it up because now everything is so anonymous that you can be a total piece of shit and never have to worry about any backlash because everyone is untouchable. Even if you did get an entire server to exile you...you could just change your name, or change servers.. It just takes a lot of the immersion out for me because, "who cares, I'm not accountable."
