in T1 when i played my Fed alt in T1 PvP DM Space, i saw the fed team 60% the time being non grouped. No team work, and no help from other players when you got focused.
Also Feds dont focus,support a friend with CDs, nothing.
So thats pretty much the reason Feds loose. If 5 Feds focus fire on one BoP, the BoP will die in seconds if it gets no help, but it always do get help from engineering teams and science teams. So Feds loose.
