Well put as usual Scourge but you can't explain this to the players that get carried all the time and hope that they'll understandI've explained this to you before: There are teams with whom you simply cannot coordinate. It has nothing to do with ego - you can have a skill or language barrier, or simple refusal to communicate, as is often the case with many of our mysteriously silent regulars. Once in a while, you may get one or two people that can coordinate, but on maps like Niven or McSwartzly it's simply not enough.
And if you don't get those people, lights out - Four hours of RU farming and head-bashing. That is truly pointless.
