Honestly, I think Terran/Protoss would beat Terran/Zerg anyday. Why? Because in a battle like that would depend more on skills and spells than in numbers alone. And, despite Zerg does have some great spells, they are easily countered by one of the other teams. For example, both the Science Vessel (mana killer) and the Dark Archon (spellcaster assassin) are great counterspell units. As for the Zerg, only the queen is good against organic ground spellcasters such as the High Templar. We also have to count with the strenght of the Zealots, which can hold the enemy ultralisks and other melee units while the M&M/tanks support fires without suffering damage. And, of course, medics can heal zealots, as they can heal zerg. Even with Dark Swarm, zealots are also helped by it, and storm can rip anything below it. Nevertheless, it also depends on the timing of the game. In a rush, TZ would own TP, because of the cheer power of numbers. Unless the zerg was newb and didn't know how to micro. However, that's a risky situation, because if the TZ is cornered while rushing, they might very well lose the entire game in some minutes. Of course, TZ do have other chances, like Guardians protected by a buch of Devourers, Mutalisks, Wraiths, Valkyries, BCs for attracting fire, etc. However, storm can rip apart the air units, and if we add Irradiate to the equation, Zerg air equals zero. This is all theorycraft, of course, and I'd very much like to see a situation where this happened, with four skilled players, to see the result. Bomba923, multiple posting is not allowed. Since you're new, I'll let it pass and correct your mistake for you. Don't do it again, please.
