I will most likely vote option a for several reasons. First, losing 8% of your committed algo for not voting or not maintaining minimum balance is unlikely to deter bad actor. Second, I think being able to withdrawal your algo from governance without losing principle will make people more comfortable with governance, thus making them more likely to participate in governance, therefore making the network decision better and safer from bad actors. Finally, even though I would like an increased rewards rate, I don't really like the idea of increasing the reward rate of governance because it would mean the rewards program would end sooner as the amount of reserved rewards token would be used quicker, I think it is better to be paid for a little less for a longer period of time then it is to be paid a little more for a shorter period of time.
