There are a lot of matches in public games where the bomb carrier is afk for an entire round. The only option for the attacking side is to eliminate the defenders.
I am often a medic or engineer in execution matches and I find myself swapping to an engineer and hope that the game doesn’t give the bomb to the inactive engineer which it often does for whatever reason. Voting to kick the inactive player isn’t always a reliable option because it often doesn’t work. There can be 7/6 votes to kick the player and yet the votes ends up failing.
