Player skill level classifications

[Valkyrie_Lenneth]

I was under the impression that those classifications referred to time spent playing, and not player skill.

This is why raid groups are classified Casual -> Hardcore. Casual raiders spend a few hours a week raiding, midcore raiders usually spend several hours a day over multiple days. Hardcore raiders will spend most of a day progressing in early stages of a raid tier, and tend to clear the entire tier within the first week or 2.

Many casual players are just as good on a skill level as hardcore players. Its all about exposure to mechanics.
