i think the MC is important field.... and i usually have 2 strong MC... cause MC control the ball passing... and they link up the attack and defense ...well... even they might not scoring at all...but at least they can protect the defense...which mean i am not going to lose the ball so easily...so, i also seeking strong MC at all the time~ (i prefer at least one over 190cm and weight 85 in the team....strong enough to crash LOL)
