It's over. We'd predicted that we would get him this week, and after two pulls it was done. We are now the only people in the world to have killed the last boss of tier 15.
Many people thought it might be the case that the limited attempts would therefor be removed, or at least that the race would carry on for a while longer. Now that he's down, we can look forward to Method's videos showing off the fight and kill, and see what all the fuss has been about. Method have taken this last boss down ahead of Paragon, who have led the race all along, albeit in the 10-man size, and ahead of Blood Legion, Russia's Eksorsus, the EU's Sanitas and Envy, as well as the US guild, Midwinter, all of whom were on 12/13.
Congratulations to Method!
