Any time I see stats for Raiding numbers I am interested and start comparing realms, guilds, factions, etc. Typically this ends in me confirming something which I felt was already half true in my mind, or gaining a deeper level of information about a known real impact. That said, anytime I see stats I also assume that somebody is lying about something. Human nature.
Today I saw a page for the PvE Raiding stats across all servers for characters which had killed at least 2/16 heroic bosses on 11 Dec. This means our server Nagrand-US ranks 189th on the list, with only 38 characters killing 2/16. That is across the 394,805 guilds and 25,581,509 characters in their database.

By comparison the high values were in the 500s and 600s characters on some realms having killed 2+ bosses, 147 realms with less than 10 characters, and 87 realms that have not killed any at all. The “high” servers have also got many guilds which have 14+ of 16 bosses in hard modes for Tier 14 raid content. These guys are awesome, and I’m jealous.
There are also 60 realms where there are greater than zero but less than 10 characters who have killed 2+ bosses. Considering the minimum raid size is 10 that means that transfers must be occurring with some regularity. How else do you get 5 characters on a realm who have killed 2+ bosses on heroic?
Some of my old servers (Feathermoon-US) is 0, Eonar-US has 30, and Sumamar and Earthen Ring have only 15. The average is roughly 47 characters per realm who have killed 2/16, but then the median is only 25 telling us that there is a skew in the distribution where the leader realms drop off drastically from the top, very quickly into the average, and a very long tail which has not.
Now our guild has not killed any Heroic modes as yet (soon), and while there are only 28k characters who have, I don’t feel too bad as we are gaining ground. Would I like to be? Of course.
(update) What does it mean?
Well not much in the broader sense, just that it was interesting in terms of a gauge for where raiders are in the content. Seeing 10,000+ players have run through heroics, but many realms have very little heroics implies to me that the “end” of T14 is a significant way off yet. I’ve read rumour of the next raid in 5.2 being an Ulduar style raid, and that is exciting. Timing wise I hope that it is a long way away so we get the opportunity to strike through the current stuff.
Happy killing.
