Not really, if our group does 4 man gr 80 and I later do a 4 man 85 with some other ppl the 3 initial ppl will show up w/o me on that leaderboard spot.
Looks like Blizzard is really clamping down on cheaters in Season 9, and I have to say I applaud their efforts.
If you take a look at the 4-man leaderboard, it's easy to see there are hundreds of accounts now missing.
Out of the top 100 clears, there are only 102 people, rather than the expected 350+.
Don't cheat guys, it doesn't pay off.
For example 13th place 4 hc season 9 gr109 shows as 2 ppl but the 2 others did g110 and are displayed in a result above.
This is not displayed on the bnet rankings webpage, you have to look at the leaderboard in game to verify.
However the group in spot number 1 is missing a monk and since you cant go higher it's fair to assume there were reasons.
