Step G just makes it so that sidestepping is the best form of defense in SCII since it negates both high and mid attacks.
Combine that with many safe attacks and you have the reason why, at least among those who really broke the game down at high levels, SCII has a reputation of being a low risk game.
Low risk game with really good attacks. Good times.
