Every time I've played siege since this update, attackers and defenders have been winning with roughly the same frequency (as opposed to before, when attackers won 90% of the time). Bravo!
I didn't pay attention to the autobalancer; has it been tuned to be less aggressive? No one should be switched more than once per map on siege.
Most people's biggest complaints about siege have always been 1. attackers always win and 2. you get team switched every round. If both are fixed, NA siege might actually start to populate now.
Thanks Fips/Teeth/Eli/Jacko/whoever else helped make this happen!
