In order for Terran to scout he has to micro reaper and make reaper 1st .
trade off ?
Toss as an equal terms at start just scout with his 1st probe . in order to block this terran had to make a 2nd block with depo.
Now if adept is in your base already he will like to spam skil just to check your front terran on the side most likely to scan or dive with his reaper .
Now what i wanted to address is simple how come a hallucinated phoenix can see everything in my base . A scouted terran base basically tells everything already by just looking at the taken gas or number of building but a terran scout a protoss base does not really matter.
WHat i propose is A toss should not hallucinate a unit if a toss have no production for it so it will be a trade off indicator if he already have a stargate meaning toss cannot hallucinate phoenix if he has no stargate .
So terran can basically proxy too with one gas or two gas. hallucinated phoenix basically see everything already makes it non stargate openers making the game boring and not suprising also on toss side .
