How do you determine the amount of rounds affected due to mental?
And how do you determine the amount of rounds affected due to economy? 1 round for economy? Who says they win the next round? What if they do and send them to eco, cycle ults and win 3 more?
You say taking mental into account can't be done because it's just speculation. But it's the other way around, that is exactly the issue. You can't determine how an issue like this affected the rest of the game in so many levels which is why you don't speculate and say "oh it affected 2 rounds" or 3 or 4 or 5 or 6, who knows, instead you do not speculate by just replaying from the issue
Btw Imo the correct solution was putting out a public statement apologizing for the mistake and probably firing the mf that took made the decision and then just moving on
