Yesterday, I joined a group on my 305 Titan for a normal oryx. I have completed the raid a few times with multiple groups and know most strats. 20 seconds later after introductions and in the middle of bantering with them ... I am removed from the fire team and party. No warning and no explanation. Know what I did? Joined another group and had fun killing Oryx. Just ignore those players and move on to a fun group.
