I play solo and usually do my own thing. Control has been my main game since D1 so I am very familiar with how to play. I usually have 1v1 fights in D2 with the exception when their is a fireteam of four people and they all run together elsewhere like butt buddies. When that happens though you should figure out a strategy that hurts them. If two people attack you and kill you then that is only +1 kill for them. If you kill both of them then it is a +2 for you, assuming you both only have 1 zone controlled.
