The most fun part about WvW, in my opinion, are open field fights. To that end, as friend has suggested to me, the ppt for each objective should be cut and the amount of points given for finishing someone off should be raised as such:
camps = 3 points
towers = 6 points
keeps = 12 points
SM = 24 points
Finishing = 10 points
With a change, along these lines, WvW would become more combat oriented and less “siege up and camp inside a keep/tower” oriented. Players would also have much more incentive to finish opponents off rather than grind them down, making group fights much more interesting.
