How Do I Practice SC2?

I have been playing alot of 4v4 to practice my build order and macro/micro, but get called a noob when i tell people thats how i practice. Any Ideas of another way to practice, i dont like to practice on 1v1 because alot can happen too quickly and it makes it hard to learn or actually do something. Any help will be greatly appreciated.
