Since you're all hot for the number, plenty of goons don't live in Dun Goonheim and aren't part of the town, plenty of goons at the time were in old Goontown, plenty of goons at the new location weren't even killed because they were away from the town proper resource gathering or :lo'd, and so it goes.
But to the point the specific number's completely irrelevant in that it could have just as well been one man against 100 players and he still would have killed them all.
Just like there could have been 100 Jon's and one Blaze or Raephire would've killed them all.
That's why the new influx of players wanted a reset.
