If the answer to your question is yes, then you've arrived at the right place. A Starcraft II player named Joana has written up a very helpful, very cheap guide on how to improve your micro and macromanagement skills as you play against other human players on the Starcraft II Leagues and Ladders system. She also details build orders that the pros use to devastating effect against their foes.
How do you know that she's the real deal? Well, besides showing that she has a clear understanding of the metagame, she also posts a screenshot evidencing her top-level skills. Once you purchase this guide, you'll be on the way to reaching (and perhaps even surpassing) her.
For those of you who could care less about the ladder, Joana's Starcraft 2 Strategy Guide also has a complete Brutal difficulty single-player walkthrough, which is something most of the other Starcraft 2 guides neglect to have. So, you have a complete single-player and multi-player aid to your dominance when you buy this guide.
You have a full 60 days to try it and if, for some reason, you don't feel like it has lived up to your expectations, then you can ask for a refund (although I don't know why you would want a refund since this is such a good tool, but to each their own).
So, what are you waiting for? This is a risk-free deal and this kind of information isn't going to come any cheaper! Matter of fact, Joana's been thinking of raising the price of this guide, so you might want to grab it before she commits to that line of thought!
