That's the gist of it, but there's a whole lot of finesse to it. You need to decide what items to get (for whatever situation you're in. Depending on their hero, your hero, the number of people playing, etc.) what skill build to go (same thing as for item build. Depends on enemies' heroes, number of people, etc.) when to use skills and conserve mana, and ASDFASDFASD. A whole bunch of stuff I still haven't learned (although I'm not bad).
Also, anyone mind telling me how to fix Hamachi? ;-;
EDIT: Fix'd. Ready to play anytime.
We should have a DotA tournament of 1v1, 2v2, 3v3, 4v4, 5v5 (not all) some day. :3
