The correlation between Flame Leviathan being tops or Vezax being tops seems to be a matter of the day of the week. Monday night leading into Tuesday morning, Vezax and Yogg-Saron reign supreme. Wednesday and Thursday when everyone has a fresh Ulduar ID? Flame Leviathan is ahead significantly. Makes sense. 'Risen Ghoul' is consistently near the top, too. Nerf Death Knights plz k thx.
The most interesting stat of all of these this time around is certainly not most dangerous mob, though. No sir. The Most Completed Quests section is hilarious. You can see the effects of this past Tuesday's lengthy downtime for certain battlegroups. How can you tell? Well, the date of the data is when it was uploaded to the site. It's the data from the day prior, however. The data listed for Wednesday (which is what happened Tuesday)? There are no daily quests in the Most Completed like there usually is, no sir. It's the entire Death Knight starter quest chain. Yes, that's right, you can actually see how many people on North American realms rerolled throw-away Death Knights on different realms because their server was down. The very first quest, In Service of the Lich King, was completed 64,152 times.
