Whoever says zerg is weak is kind of stupid....Zerg doesnt with strong units. Any Zerg player worth his sh!t knows that zerg wins most of the time by simply outnumbering opponents. And keeping it that way, endlessly. So no, toss does not own zerg. In fact, no race owns another on any map.
Toss has some great thibgs to stop zerg with, however, most notably Psionic Storm. To use this effectively you need at least 10 or 12, at least against anyone I know.....on my zerg end of the stick, usually get about 10 queens (yes queens) and broodling the High Templar form afar. Or, with Terran, EMP their energy ^_^.
Terran is very good on money maps, despite what you think. Tanking up the center is relatively impossible to stop if the Terran manages to get enough Turrets and get about 12-14 BC in there. The BC can stop even zealots from getting close. In a 2v2, a Terran can go straight turrets and Tanks while his Protoss ally gets a bunch of corsairs (with ups) and any ground unit they wish.
Zerg has some dificiency, however, as the only real unit for killing tanks is Guardians. Dark Swarm still only blacks 50% damage, and if the Terran player has about 10 vessels they can destory your guardians extremely quickly with Irridate. Very complicated, fight Terran with Zerg. If the Terran finds you quick and catches you teching, he can M & M you and raze all your work. And if you go for lots of Hydras first, or Lurkers, the Terran can sit back and get tanks then move in before you even get a Greater Spire. With about 10 tanks and some mariens of Goliath for support, your hydra will be slaughtered. Given this, you have to find a neutral spot whereu get eniugh hydra or Lurker to stop Terran rush yet tech fast enough to get Guardians, or Defiler if the Terran gets less Tanks. And then there's always running out of gas.
There I made all the arguements i wanted to......most of this applies to Money Maps, which i know best.
BTW all those chumps who think Money Maps are newbie, just because you suck at them doesn't mean they're newbie and the only reason money maps have the reputationt hey have is because most of the people who play them are newbies. I am not, and if you tried to play a competitive money game you'd see how newbie we are ^_^.
MONEY MAP REVOLUTION!!!
