I mean all of this is proving my original point, which is
accurate data for 25 vs 10 man is difficult to ascertain. Also looking back at old threads on Lei Shen it's quite clear that 10 man mode was definitely easier than 25 which really skews the results here.
If we take a look at SoO Wargraphs shows a higher spread of 25 Cutting Edge Achievements vs 10 man
https://www.worldofwargraphs.com/glo...category-15271. I wouldn't even say that's fully accurate by itself either but that further feeds into my original point.
Yea certainly interesting to see with them, would've expected a 10 man kill much sooner but oh well.
Difficult to compare though really considering Blackrock foundry lasted for ~4 months as opposed to ToT which was ~6 months, plus you had things like sub drop offs and initial difficulty of Blackhand.
