lol, ya maybe if you had a heal and AOE macro going then maybe you wouldnt die. The people I usually get killed while AFKing are shooting like lvl 25 NPCs, but ALOT of them (10-12). I dont believe they use a heal macro though and they were just standing there spamming a HW. (I get a sense of satisfaction after I kill them lol)
Anyways, as for the running around, you can just do /follow (NPC Name) and you will follow the nearest NPC of that type. It usually works best in an open area, and yes sometimes you will just stay running into a rock or wall or something, but it makes it look a bit more like you aren't AFK (unless you do end up hung on that rock lol).
I usually dont do stuff AFK, I just sit at my keyboard watching my char do the stuff for me lol
