The title "realm population" is completely misleading. Blizzard uses the mechanism of "total characters created" to calculate the population of a realm in World of Warcraft. My original realm - Agamaggan EU - died years ago. It wasn't that people would've migrated off. In fact, they just stopped playing their characters on that realm or completely quit the game. Using the guild-finder, you can observe hundreds of level 25 guilds with hundreds of members, causing this "medium" population-mark.
When a newbie chooses a realm to start his path in, the title "population" is completely misleading and causes him to lack most parts of the game due to:
- Dead economy, auction houses are empty, nobody is using trade channel
- No raid groups to current content
- No social interactivity or friends to get to known with
Why does Blizzard do this? Isn't the satisfaction of every customer their top priority? No, simply not. What you don't know, doesn't hurt you. And then we all know what is the result of LFR-ish tools that you may join in from multiple realms.
- Offer real-time population calculations based on recent logs
- Force realm-merges to completely dead realms
- Offer free migrations OFF the dead realms and shut them down permanently
Finally, I decided to add some pictures that were taken on this "medium-populated" realm of ours. It's your own judgement whether you find the title misleading or not.
