Casual =/=bad is false. People saying they play five or more hours a day and accomplish nothing are just bad. The big bad elitists can spend five to eight hours a week to beat all the content.

Casual is someone who has time constraints and can not put in much time for playing. This usually leads to the casuals not raiding, which is where this line got blured and bads began claiming themselves as casuals since they also don't raid. I have known plenty of casual players in mmos that were still doing progression raiding.
