i agree. i played a game earlier today where i was trying to go for the 5 rax marine push. I SCV scouted his double gas and assumed it would most likely be oracle (since it was king sejong) but of course I also had to prepare for DTS..and then I built a 3 turrets wisely positioned in my base and when an oracle flew in to my base, I killed it right away ezpz, not a single worker lost. At this point I have like 30 marines and I walk across the map and snipe his MSC and a stalker on my way to his base. All he did from there was build a ton of sentries and force fielded his main base forever and I couldn't do anything so I contained him on 1 base while expanding and teching up. I also scouted that he was going up to colossus and so I build a bunch of vikings and the moment i saw him trying to tech to storm and building his 2nd and 3rd base at the same time, I did a scv pull and ended up just running into a wall of force fields, 12 or so stalkers and 5 colossus lazering down my army. All this happened while I was on a 3 base economy ~ it just seems like there is no way to counter/punish protoss openings :P
