It's not "prolonging the inevitable," far from it. The last red getting crits gives them a huge advantage and a chance to make up for their team's lack of damage. Implementing a time limit like this just gives hale an excuse to hide instead of actually hunting down the last red, and heaven knows we have enough camping hales as it is. If a red is really delaying the round in a manner that would warrant use of this system, just voteslay them.
