I did this once. Got placed with 2 32s on Sepiks Roc. I go forward to the stairs, look back and they're a mile behind. No problem, they're working their way up. I get back to the laser tripmines and look back and they're out over near the entrance to King's Watch (in that general area). I start to get suspicious but keep playing. Two waves in, they're still out there, and I realize they're chest farming and planning to piggyback off my solo-ing. No way is that happening, I thought. Decided to run into the lasers. "You have been consumed by the Darkness." This brings them up to me. They immediately run off back to the Rocketyard. I smile and watch and wait for them to reach it before walking back into the lasers. Another wipe. At this point they know I know and start punching me. I dance at them to show that I'm not carrying them. They get mad and go to Orbit. Good riddance.
