We’re all aware of the “Bosses that remained unkilled the longest” statistic. I’ve never really liked that stat because there’s far too many factors that contribute to it other than purely how difficult the boss is, and especially when you compare to things like Vanilla when It was a completely different type of game, It’s just really not worth much (and also because many bosses in Vanilla and Early TBC were mechanically broken and/or unkillable)
So I’ve made a list based on wowprogress statistics for the time taken between the world first to the world hundredth
I think that this statistic is a much fairer comparison of difficulty. Once 100 guilds have killed it you’ve gotten a good sample of how long It’s taking, and you’ve got good coverage of extremely hardcore in the top 1-20 through hardcore in the middle and then semi-hardcore only raids 3-4 nights a week range in the 75+ bracket.
These statistics are not perfect by any means, I can think of two major problems and they have to do with the number of guilds raiding throughout particular times in the game’s history:
1) The games number of players, and therefore number of guilds has changed and fluctuated over time. There is arguably far less turnover of players in the top 100 guilds in the world, but this is still something to consider
2) In Cataclysm and MoP 10man was considered equal to 25man. You can obviously have more 10 man guilds than you can 25man guilds, so comparing WoD+Legion+Wrath+Sunwell which were all 20-25man in raid size to Cata+MoP were 10man guilds were dominant is unfair on Cata+MoP as there was more guilds raiding during that time and the stat is only a snapshot of the top 100.
These stats are taken from wowprogress, and wowprogress only goes as far back as Sunwell so sadly Kil’Jaeden is where it ends.

**Progression of this boss occurred over Christmas + New Years, inflating its number of days taken
Below is a google doc spreadsheet that contains all the exact dates & times of the kills, aswell as a separate page that contains the 1-100 stats on all bosses in WoD and Legion.
