No matter when you started playing World of Warcraft, if you raid, you've probably felt the itch to visit every last dungeon you can. Motivations vary; some players want to rack up more achievements, some are avidly chasing each scrap of storyline, and others are in search of transmog gear or just plain bored with the current content.
Let's talk about the different ways players enjoy WoW's raid content, both current and classic. Have you taken a turn through every last raid instance in the game? Are you enough of an old-timer that your total includes 40-man and 20-man versions of early dungeons? Which dungeons are the most difficult (or inconvenient or hard to schedule) to revisit today? How many folks here have completed every last raid at the intended level?
