The key to know that which unit other team member is using is the J key if you hold it you can see what other units is in the team and you can easily balance the team out. People do not seen to care about what others are doing until some building is blown up and start to blame each other for not defending the base. I have seen this sooo many times and I want to go out and kill some people on the other side. Most of the time when I am not in the base and I caught in intense fighting if someone sneaked into the base something will be blown up. It is sooo annoying. Cycle the team member as dedicated Eng is definily needed.Zukkov: did you buy the MB and the heatsink as a combo. make sure that you have the right heatsink for the MB or it will not fit or work not as well. Another thing to try is to push the heatsink right into the MB straight down without put one side in first.
