Can't say I've ever experienced regular disconnects; typically when I do experience connection issues, it IS on my end, or it's a server issue that's affecting everyone connected.

This was definitely a gripe back at 2.0 launch before they implemented the AFK timer for awhile; however, you still had some creative people who used third party software or macgyver'd something together to press their controller/keyboard and keep them "active" while they were away at school/work/whatever.

You might knock a few afk people out by putting the timer on full time, but more likely than not you'll just turn them into dancing puppets.
