A bit of explanation - when i saw he's fast expading i decided to go DT's that was pretty succsesfull i think, but I'm not sure about gas steal in this situation - it don;t really help DT's. Then game gone standard, and I have no idea what was wrong despite my Arbiter control. But how the duck I'm supposed to use them - if i send them first to froze tanks before army arrives they'll die to goliaths. If I send all togheter, all died. So I'll be grastfull for any tips, particulary on arbiter control, but on this game and PvT in general as well. I can also send more reps if anyone is willing to help, but I thought that one will be enogh for now.
