CoYoTeAfter i46 when all the eu teams got smashed because they weren't ready for the na aggressive play they adapted to counter/recreate it and in turn smashed hrg at i49.
to be fair, hrg didn't really get smashed as they got 3rd (i think?) at i49, but the whole esea quick-fix lan definitely messed with their strats and playstyle since the quick-fix was already banned in etf2l (again, i think?) and stayed banned for i49
