Co-op AI Difficulty

So I recently got back into Starcraft after a while and redid the campaign then turned to Vs. AI matches. I was disappointed that there wasn’t an option to change the difficulty of the AI and I would lose every time because I would get marked by an AI with unrealistic resources and starting units of 100. It doesn’t seem like that could possibly be the default AI. Is there any way to change this? I can’t take being bum-rushed by 100 units in the first 5 minutes any longer.

I’m searching everywhere for someone to teach, the nearest I got from it is using scmdraft2 to add trigger that run Insane AI Script in a custom map.

Unless you have a custom difficulty set to insane, the AI uses the same rules that players do minus the map hacks.

And all you really need to do to beat the AI is to learn basic walling and defensive play so you can’t just make 50 workers like whatever you’re doing and wait for the AI to roll over and die.
