The autobalance went off but it was hardly satisfactory. It detected a score imbalance or something like that and scrambled the teams between rounds. The map was a Payload map and the score disparity was due to offense/defense. A score balancer like this makes sense in ctf or cp, but the trigger should be more like 4 wins in a row -> scramble teams.
Also having a votescramble is basically worthless because there will always be 1 or 2 people that rage about their team and it seems like many people will assume that it is nothing more than someone getting owned and voting for a scramble because of it. A more versatile and logical auto scramble would be much better.
I also feel like this voting behavior is the case with rock the vote as well. Everyone has their most/least favorite maps and I would be quite happy with a simple standard rotation that's a mix of ctf, cp, and pl.
