First of all what i would have done is two turrets. with a sp-sp-barracks build as it was release. The arbitor gets hit hard even by a single turret. If you did manage to kill one i would have had 5-7 flamers waiting for you to either waste your rage money or get toasted. Then i would have moved to a tanks/flashbang build assuming you would go hunters. If I scouted and noticed you didnt get hunters i would still pump out some flashbang flamers as they will come in handy when you do switch :P @ that point its a counter game of me making the correct counters. Hunters - flashbang, tanks. Wraiths = Tanks and spartans/flamers , banshees = wolvs/flamers, turrets.
This guy made some huge mistakes. First off he built his first tank at 7:30. I would have ATLEAST had 3 -5 at that point. second he built an S*** load of spartans and warthogs which = food for arbitor. I only build hogs against PoR NEVER EVER EVER against arbitor. (not saying its the best way just saying that i dont, maybe im the newb)
Those are just my observations.
