The irony is that easy mode isn't really easy. I'd actually say it's more akin to turning off the AI's common sense, particularly because if any Gorg Battleship actually pays attention to you for more than a few seconds, they usually wipe out your entire fleet within roughly half a second in the early missions where you only have the Angelwing and two destroyers.
It goes kinda like this, actually:
Gorg ship: Oh look, some guys are shooting at me. Okay, I'll shoot back.
Angelwing: Well, the player didn't order me to disable the shields, and instead told me to shoot the ship with bubble/energy shells/crisis ETs, so I'll just fly around like a dumbass and take the occasion potshot at this Gorg ship.
Gorg ship: Holy shiet, this guy is trying to take out my shields! I better kill him!
Angelwing: *Explodes*
Me: *facepalm*
It actually reminds me somewhat of the Combine AI in Half-Life 2: It's actually quite smart, but Valve is terrible at map design, so there's all this stuff and code everywhere that confuses the hell out of them and makes them act stupid.
To be frank, I'd say it's fixed now. Combine soldiers are merciless with me: They set up ambushes and try to flank me often when a shotgun equipped soldier is present so he can get into range and kill me with semi-automatic fire. I've noticed they're really quiet when they're on "alert". But back to being on topic.
