Yes they do OWN terran, even if they see them coming. The only they can beat them is to prevent carriers from being built. Goliaths aren't that great against carriers. Pros(Grrrr, in particular) have beaten many groups of goliaths with carriers, particularly because goliath's mobility sucks. Terran LOSES almost consistently to carriers. Go to
www.wgtour.com before you make such claims. Most PvTs are won using carriers. Or visit the battle.net board. We just finshed discussing carriers v terran goliaths/wraiths. Terran counters to carriers suck badly, which is why they're so useful late game pvt. You need to learn more about the game before trying to argue with me.
