I'm not sure I understand what all the fuss is about. How am I harmed if someone wants to camp a chest or two for drops? It doesn't affect me or my game in any way. This is not an MMO. No one is gaining any kind of an advantage over anyone else here.
Frankly, I don't think it matters what people do in the game or how they want to play it. If they're enjoying it, more power to them.
