The only thing thats good about the zerg is that its easy to rush your opponents and wipe them out before they could get there units and defensives up thats the only thing there good for
The Zerg's ability to counter any type of situations in a timely fashion is what makes them efficient; if your skills as Zergs can only make you achieve a quick rush at the start, more power to you... you need it, lmao...
Well, any good player need to grasp how the other races actually work in order to properly counter them; managing the terrans is where I do not seem to fit, but they have great units
It's all about preferences as skills will make you win.
