Personally I prefer the newer scoring system.
It means that if the round was more equal, ie. both teams were able to conquer the opponents base or neither was, the score reflects this.
Or if one team conquers the others base and manages to hold their own too, they are rewarded with more points.
How this helps the losing team I don't understand. Sure it gives them more opportunity to catch up, but it also gives the winning team a greater opportunity to break further ahead.
I also prefer the old style where 2 attackers can conquer the base of 2 defenders simply because I think attacking should be encouraged over defence. So the more attacking players should have the slight advantage.
About ctwf, I honestly thought cycle_rubber_wall_shrink was 1 and had been for many months, I checked and it turns out it was 0.5, higher ping players may notice this setting more than me. It has now been changed to 1. Just for you Durka
