Q: What is leeching?

A: Leeching is when a much stronger player groups with a weaker one in order to help them gain levels faster. The stronger character is doing the majority of the work which prevents the person being leeched from dying often. There is benefit to both the person being leeched, and the "leecher", as it helps the leeched person become more useful in groups to the leecher in the future. It is recommended that the leeched person still take steps to learn how to utilize their class properly otherwise they may become high level too fast and be unsure of how to use their skills.

Leeching is NOT when one person levels another while the person being leveled is away from their keyboard, that is autohunting/autoleveling.
