I concur that multiboxers are probably not your typical hardcore gamers.

I will take me as an example: 10 years ago I was hardcore. I could easily pull 24hour sessions when needed. 5 years ago I would still try to be hardcore. As I played Daoc on US servers I had to go to bed when I got home from work and wake up at midnight to raid/pvp. Thats when I started multiboxing so I could do everything in my own time.

These days I have a well paying job and 2 kids and other interests outside of work. I do not have time to suffer the fools when playing so I box exclusively. I havent done a single raid since 2.3 since I made the switch to EU servers (not even VoA or Ony).

I do miss raiding but I need to find a bunch of mature gamers in a similar mindset as me ie people that play infrequently but take playing seriously when they do play.
