2vs1 is hard unless their newbi arse i have a few reps of me trying to 2v1 i always lose tho coz their gosu bums -.- but i almost win them but (ALMOST)...

What you mean by cannot create more units? is it when u have not enough supply? or there just so many men on map that u cant create any units even if u have supply which happens on 3v3nr 20min?
