"they didnt lose because furia played good..."
Furia played better, there is no excuses.
CSGO is based mistakes, enemy makes u you do mistakes and then use them.
No one can play without mistakes.
Next time do more research, it was kinda clear if it goes to third Furia will come out as winner.
Complexity maybe got firepower, but in heavily tactical maps they are behind every top15 teams. (overpass, nuke and train)
