ok first get MT and DR
once those have capped have about 4 people at each base
then have about 2 in the middle
have the rest rushing one of the hordes bases and if you capture that one
go to the only horde base and rush the GY the whole time and the people in the middle well keep getting the flag
the people rushing act as a disrtaction to the horde so alliance can get the Flag
if this helped you at all just leave a comment saying thanks
