I have dual monitors set up, as many other IT people do. I sometimes watch Netflix or something else on my other monitor while I play. Just because I'm not moving doesn't mean I'm not there, or even if I wasn't, who's to say I can't use my speakers and turn the volume all the way up to hear when the queue pops? Just because the DPS queues are 30 minutes long should not mean I should be forced to play for 30 minutes before I can run my dungeon. This is specifically why I said #2.
Edit: I also am not opposed to an AFK timer, in fact I'm all for it. But that doesn't mean it should be as simple as *player doesn't move/send command for 10 minutes so log them off without warning*.
