The last time I have been livestreaming somebody wrote in chat that "I play pretty greedy, never scout and I would just die to basically everything"
Apparently, there is a big discrepancy of what scouting actually is. In essence, I would define scouting as receiving information by sacrificing something else.
As an example, I get information on the Gastimings of my opponent with a probescout, but on the same time i sacrifice economy for that.
I get scouting of my opponents armymovements whenever i take a watchtower, but i might fall into risk being catched offguard losing my unit. Obviously you are more open for attacks if your army is more spread out.
So just because somebody does not probescout, it is just wrong to say he is not scouting. Anyways, I explained it to my viewer and thought about doing a conclusive guide about the general idea of scouting and timings in PvP.
In general, PvP looks like this for me, going into the game, you have a big picture in front of you, this big picture is everything your opponent could go for.
Let this be: Proxygates,Warpgatetimings,Stargateallins,....
Now your job as a player is to narrow down the picture to a point where u can make (safe) assumptions and react properly to what your opponent is doing. It is not about finding out about what your opponent is doing, I would rather describe it as "narrowing it down to the most likely thing".
I have worked on this topic for a long while for my own play, and now I want to share it by sharing this Guide. I hope it helps, constructive criticism is welcome!
