SpaceCadetI feel a Golden Cap should be decided in 2 possible ways.
I believe this would also lead to more exciting pushes from last when teams get desperate as well as new off-classing strats to dislodge a team that decides to "park the bus" and defend a 2nd point with things like Heavy/Engineer.
If you're defending last you already have enough issues in OT, I don't think adding the winning team parking the bus on second really helps
