No server should be ahead by 150K, not fun and ppl give up. It should be more difficult to stay on top and if you do it should be more rewarding. Golf and horse racing has a system called handicap. Something need to be done as WvW is were its at.
Just to spell it out: The winning server moves ahead in points, the more point they get ahead of the other server the more debuffs they get and therefore they become handicapped. Now at the end of the week if they managed to stay ahead with all the debuffs they get greater rewards i.e more tokens and gold.
