Halo Wars 2 Multiplayer AI Difficulty?

[Accessing]

Does anyone know what the AI difficulty is? At launch the game you could solo vs. 3 AI and I just observed an atrocity that is a teammate losing to 3 AI's, I was already out of the game since I had to go AFK for 15 minutes and that was enough to come back to a destroyed base in the early game. Where my teammates were left to eachother one had disconnected midfight, likely because he was low on resources to replenish ultimate units while the other fought on until they surrounded his last base and he lost. 

Back in the day you could turtle up a little bit and fend off 3 AI's I don't know if thats changed or there is a skill issue.

It's Heroic, I am an idiot and didn't see it in the post game report. 

With that said, I think the balancing updates have made it harder to beat them now than they were before. 

Which is a good thing at the end of it all
