The current system does not incentivize people to build max defenses at all, which is a downside. There is also the huge time sink issue, which really needs to be addressed in order to get new players playing against the seasoned veterans. Why would I want seasoned veterans to play against new players? To expand the pool of players. Besides, the seasoned veterans would still win because they have better skill and everything is on a level playing field at that point (max offense and max defense), right?
