perhaps you would like rewerse stat points distribution for guild war attacking, but keep the current distribution for defending?
that way it would be even much more fun as the current paragon would have the least invade stats so guild war invades would be hardest for him - therefore hardest for him to keep his status of “earned most guild war points” to keep being paragon next week
= paragons would be changing each week a lot 
that would also motivate everyone much more to be buying those stat points as everyone will be benefitting equally in total (considering defense and offense)
