Note - I'm thinking about writing two more guides to complement the first two. One will be on basic Zerg unit compositions, an overview of all of our units, and how to counter all of Terran and Protoss's units. The other will be a very basic overview of Zerg tactics - harassment, containment, expansion, aggression versus defense, that sort of thing. If you think you could benefit from one or both of these, let me know by replying to this thread, and I'll get started on them as soon as I can.
Yes, would love to read your other guides. This was very helpful.
