my favorite place to be in general is "Henge of denravi"
my 2nd favorite place to be sometimes is "Serenity Temple", but thats just to be somewhere near low lvls, and stand afk there
denravi however, has the npc's i need, and much better looking, also not much people, so no lag if its a "bad connection day"
the perfect afk, stand (stand while chat) and think-about-stuff place... for me
