I am curious - when you're playing on the world map-- is an inactive player one who does not have a banner or crest on their city? I have several in my area on the world map who do not have crests/banners. Those seem to get replaced with a "hole" in the ground with gold in it and shortly thereafter, someone else takes over. (I'm still pretty new to this- can't even make topics on the forums. lol!) Thanks.
Also in the "guild" I am in, I've been trying to determine if I should stay in it or find one that's more active. I only see a few regular players who seem to do anything in it. Even the guild owner seems to have been inactive for a week. (That could be RL issues, or someone just bored with the game. Happens. I know people who quit and resub WoW all the time and I play that also.)
