Just beat this weeks Nightfall for the 3rd time as my Hunter. Got Mask of the Third Man... at some expense to others. I joined up with a couple friends towards the very beginning of the Strike. When we got the final boss, we had his health pretty low when my internet decided to cut out on me, kicking me and my friend out of the game. One guy wasn't kicked, so I was able to jump right back in with him... then HE lagged out (he'd been having connection problems the whole game), and my friend was still having trouble getting back in. So then, I was all alone. The other two guys weren't coming back, or so I assumed, and I went into panic mode; the boss only had a little bit of health left, so I popped out of my hiding spot and unloaded on him with Ice Breaker to finish him off. I succeeded, the Strike ended, and I claimed my reward. Then, my friend sends me a message asking to invite him back in. At that moment, I immediately felt like... "Oh man... I'm a d***..." Should I have waited for them both to rejoin before killing the boss? My friend was taking real long to get back in, and I was freaking out...
