the secret of team games

i'm a singles player myself and every time i tried a doubles game i've been slaughtered.
i've teamed up with all kinds of players ranging from cadets to majors, i've taken the role of coordinating the team as well as listening to orders, i've had bad dice and good dice and played on all sorts of maps. and yet my profit from doubles games is -51 (yes minus) and my win ratio is 46.43% which, funny thing, is lower than my singles win ratio (46.48%)
i guess what i'm asking here is what's the secret to team games?
do you coordinate through various messengers? do you use the game chat? do you play only one map with the same player until you learn it perfectly?
i don't want to become a doubs or trips player. i'll play them occasionally in tournaments and i'll mainly stick to my singles (77.17% of my total games). but i do want to find out how other people managed to turn team games into a success story.
