Since it's too hard to find players for 2v2. So I decide to spent sometime with AI in 1v1.

I found Normal/Challenge/Tough is nothing to me. Just build Factory and spam T1 before AI made to T2 then it's end.

What I found something wrong are Painful and Insane.

Painful and Insane AI are really smart. If they can't take advantage in ground fight,they will start building bomber to bomb your

Metal Extractors, just like playing with a real player that trying to attack your economy buildings which is really great. 

But If AI lose the VP fight and Aircraft got destroyed by players Anti-Air while trying to destroy Metal Extractors.

AI seems to give up because no matter how much resource they have, they are still going to lose by VP point so AI will trying to take VP point back with suicide attack by spaming T2 units and player can just watch the killing show If built HEAVY DEFENSE at VP.

Would it be more fun for AI to building Dreadnought to counter T2 units rather then just spam unit and suicide?

Since they have so MUCH RESOURCE to spent but I never seen AI build any Dreadnought if they are losing.
