A good player destroys their opponent quickly, and makes decisions without delay.
Players: When a course of action is decided upon, the outcome is already determined once the action is decided upon. The player who can see the outcomes of each decision is the player who can destroy their opponent quickly. Those who have studied every outcome of a situation presented in an MMO based on the classes or professions involved in the decision point will be able to make informed decisions that will always lead to victory. This is an essential difference between a mediocre and a great player.
