Casual Instance Running
For those not inclined to PvP (or to augment their PvP activities), the bulk of their end game is spent in casual instances. These instances are capped at 5-15 players (about to be reduced to 5-10 depending on the instance in the upcoming 1.10 patch of World of Warcraft). One thing to point out about World of Warcraft, is that initially, dungeons can take quite long to clear out, especially if the group is not competent. An adventuring group needs to learn how to the “trash monsters” (non boss monsters in a dungeon) as well as the bosses. Due to the age of the game, the process to beating most encounters and dungeons in the game are already well known. → To be this lame takes ages.
