Morgan, I'm pretty good at nex, if you ever need a spare, just ask. I can't stand playing with the eoc for too long at a time, But I'm fine to do a couple of trips every so often.
Try vulnerability next time. Also, it's absolutely normal to fail to do enough damage with 6 people and no seismics. If you get one or two more you should be able to do it. And if anything, that shows that you're quite experienced or you wouldn't have made it that far.
Hi
