Emp wtf

This has never happened to me when playing against a person, only when playing against the AI. (on insane). Im fighting the Terran, and doing pretty good holding them off (mostly due to an Immortal "rush") and staying in my base to battle at the choke point. However, there comes a point in every match like this, after the first couple of battles, where the terran will come at me with MMM, a raven, and ghosts. I think im gonna hold up fine and then BAM!! A blue flash, and my forces disentagrate. After watching replays, Ive been able to see that the blue flash is in fact a ghost using the EMP on my forces.
What the hell???
I have tried everything. Teching up to Void Rays, teching up to Collosus, and making tons of smaller units or a few cannons. Nothing works. As soon as the EMP goes off, I'm done. The Immortals lose their shields, and become almost useless against the MMM, and my whole army instantly loses almost half it's heath. What the hell can I do against this??? Is there any counter to this garbage?? It seems so incredible cheap and broken.
Any help would be greatly appreciated.

 

Have you considered spreading out more, and targeting the ghost maybe?

 

You know, a few psi storms would take *more* than half the terrans MMMs health.

 

Wasent emp already nerfed? It isent too effective as it used to be. Defs not op.

 

I don't play protoss, but I believe Immortals would not be a good choice against MMM. I see them being used to counter tanks and other armored units. Perhaps you should be building high templars with the psi storm. But, you do have to also watch for the ghosts sniping your templars. So you should have an abundance of observers to keep track of the ghost location at all times.

I don't see the emp radius being that big either.

 

Or, DT rush.

 

DT rush dosent really work against Terran that I have seen, unless there really slow getting there orbital command.

 

As someone said earlier, psi storms would would great along with Colossi. And you could try to blink some stalkers right behind the ghosts and take them out first

 

DT rush usually works for me, even with the orbital command. By the time they realize you have some DT's in the mix, you've already one-shotted most of the marines.

 

Yeah... you're really trying to put out a fire by throwing wood at it.

MMM===get upgraded colloxen, high templars and a standard warp gate army and it will just melt. Also if you hole yourself up then you are setting yourself up for failure because a 1base terran gets more money than a 1base protoss
