Shhh its so hard to counter Terran coming out with such a good mix of units with Protoss! Vikings kill Colossus, MM kills Zealots and Siege Tank just melts down my army!!!! Please help how do I counter this
Generally if the enemy has Vikings then go HT and if he goes ghosts go colossi. Chargelots with some good forcefields completely shred MM balls to pieces, they just need to corner them so the mm can't kite. Against tanks depending on your tech path: If you went stargate, use phoenixes to render them useless, if you went robo then get immortals and keep them spread to avoid splash, and if you went citadel(I sometimes forget the sc2 name) then go HT and storm the tanks themselves since they are immobile and will take full damage. Generally if the enemy terran has many tanks and many vikings his mm ball will be smaller. See how they detection is. If they don't have a raven then some DTs in your army mix will kill quite a few enemy units before he realises it's dts that are shredding him and scans.
I have actually stopped making colusi mostly. A better unit combination vs T and Z is Zealots, sentries, a couple stalkers, imortals and Ht's.
Yeah, zealot/sentry with some immos or hts in the mix turns terran bioballs into meatballs. Edit: Yeah, my puns are simply that awsome
