I love going back to places I had trouble with and just soloing the entire map. I have seen some lower leveled players watch kill a boss and minions (If any) and not doing anything. Alothugh when I was level9 I soloed the Forest Haven Boss Gauntlet solo though. But I hate going to somewhere like Frozen Nightmare and get wiped out in 0.2 seconds by a group of Yeti's. I find survival is higher in places like The Ancient Swamps which is odd.
