"Just playing" is the easiest way to get trapped in bad habits like thinking high APM means you're actually accomplishing a lot, using the mouse to move screen, not tapping properly to keep up with injects etc.
The current pros and commentators have already snuffed out most of these bad habits to the point where it's common sense to avoid them... if you're informed. It would be foolish not to seek out the wisdom of the experienced while learning something >.>

You can message me at hanmin*632 whenever you see me on. If you want to rank up, just play the game. You can't learn mechanics from Day9 or teamliquid.
Will do. I feel like I've learned a lot from them in conjunction with playing the game, otherwise it would just be arbitrary.
