Browsing through wowprogress today, I saw that Easy had killed Mythic Fallen Avatar (congratulations to them), but when I entered their page on wowprogress, I couldn't help but notice that they were mixing US and World ranks without any particular pattern.
As I was surprised by them listing this, I went on a hunt for other US guilds that did just this, and found numerous guilds high up and far down the rankings that did just this among the NA guilds, whilst being completely absent from EU guilds. (I also chose to not look into asian guilds because they are also often excluded or disregarded from rankings in many ways).
This may be a general off-topic sort of question, but since it is World of Warcraft related to me I chose this forum instead.
Is there a cultural difference between US and EU that is causing many US guilds to list their US ranking rather than world rank, and does this sort of ranking occur in other games and/or traditional sports as well in the US or is it isolated to World of Warcraft PvE?
If this doesn't belong here, please move the thread or lock it and I will re-create it in general off-topic.
