I just did chapter one last night with one pub in a fellow who showed up at the same time as me and it was pretty easy with just 2 of us. I think I probably could have soloed the first chapter. (I'm lvl 13.5 gaurdian)
Are the chapters after that any harder or about the same difficulty. I imagine by chapter 11 it's tough as hell but what about the earlier ones?
Any idea what happens if you die during an instanced event like the chapters? no way you could fail on the main epic story line...
