It's funny when protosses try to talk about other races. They're head is stuck so deep in the sand they'll never see the light of day. My toss buddy has been playing since hots dropped just like myself. We're a couple of gold level players yet it was only very recently that he started to understand that while yes the late game mule hammer is very strong, you simply can't drop scans all willy nilly in the early game to scout what you're up against. Last night he asked me how many kills does a reaper need to get before dying to be "worth it" comparing it to an oracle that MUST do damage. It took 30 minutes to get him to understand that SCOUTING and KEEPING IT ALIVE is the main objective because dropping a scan puts you behind against an opponent that can chrono his way to a stronger economy or faster tech to be used defensively or offensively.
