Klingons have a special quest to die like 25 or 45 times to a player... could be why.
For real? That seems really odd.
K1 "Ok brave warrior I need you to go die.... a lot."
K2 "What? why?"
K1 "I got this reward if you do."
K2 "Oh ok that makes SO much sense let me dive out the air lock."
K1 "No no you got to let the other guys kill you... you know so they win and stuff."
K2 "Are you sure your not some Federation spy?"
As they said above the Klinks are probably doing "Good day to Die" and have just removed the equipped shield to speed things up a bit... *chuckles* would suck if the other members on the team aren't looking to do the quest as well.. ^^
