Yoo...you have GOT to do something about these quests requiring invasion kills or things that promote players to load in solo and do stuff like...stand next to the portal, waiting to invade, and only shoot the enemies that spawn on the bank. This weekend has been a nightmare. Please put more thought into quest lines, and how their steps might work in a multiplayer environment. Consult a behavioral specialist, if you lack people skills. It really takes the fun out of an otherwise amazing game mode when one or two people are playing for their own objectives, and not for the team.
