Most of the spawn from a level 6 map can be handled by my Guttersnipe Treasure Hunter and a mage friend. The titans, bloods, and poison elementals are pretty easy, and the balron eventually goes down to 4 EVs. However, the new improved Ancient Wyrms are very powerful. I can't seem to peace/provoke them, though I'm only 110. They chew through EVs. I eventually had to switch to my pvm mage with a reptile slayer and even then it was so slow and painful. Considering one of the fights was on Dot Island...Ouch.
It isn't worth getting a group together for the junk from a chest. Most of the chests I've done lately, I've just taken the artifact and the gold and removed the chest for the next person. I get more gems and a chance of a net from an SOS which takes no combat skill. I only did maps recently for the Spring Cleaning thing, but I think I might stick to maps that I need for tattered wall maps after this, and stock up on Level 6s in case they are fixed in the future.
