Starcraft 2 Editor: Test Melee Maps

Above the very lowest leagues, most players are very polite. They are also very terse. Some common abbreviations are used in chat for a friendly (though fiercely competitive) match.

The following expressions are often used at the beginning of a match.

• gl: "Good Luck"
• hf: "Have Fun"

The following expressions are often used at the conclusion of a match.

• gg: "Good Game". This is the usual way to concede defeat.

Short answer: There is no difference except for range and animation.

Long answer: They both do the same damage, have the same cooldown, and benefit from the Zerg range upgrades in the same way.

As for which is better to employ, the spit attack is better simply because it keeps your roaches at range and allows more of them to hit a target while leaving melee range for units that only have a melee option. Your roaches will naturally use their spit attack anyway, so there's really no difference in your micro. They just fall back on the melee attack when they are next to whatever they are attacking.
