yeah, the way how rules are chosen could've been improved, but I think it was fine since there was only a handful of rules to begin with :P
also, stunning cobb wasn't even a thing until I added it in v1.6. originally, rocks were just for distracting cobb with the sound, but I wanted to give rocks a purpose when cobb can't hear, but I didn't want to make it too OP. rocks are all over the map, so the stun time needed to be pretty short. in testing I found cobb to barely be a threat when stun time was 50% longer than what it was now
