I'd like to make the suggestion of a vote-able kick function for people in an Alert.
The past couple of days, I've seen a few people follow the rest of the team around and not attack. Some just remain at the entrance of the Alert, and others try to hide behind objects to avoid being seen waiting.
There was someone on the team, in the last Alert that I was apart of, who actually followed us around without talking, just watching us and taking one or two swipes at a few targets towards the end.
The guy on the left was just sitting there, only moving to activate the console once we finished with the combat, and one person from our team either didn't load into the Alert or took off at the beginning. We managed to complete the Alert as a group of three, but one of my Alert teammates was furious with this guy.
