If the game opponents are not challenging enough for you - why don't you get rid of most (if not all) of your buildings that provide combat boosts?Would Inno be kind enough to make the computer generated hardest players in SAV have a minimum lets say 1000-1000 % boost and preferably 1500-1500 % so players can have a true and hard real challenge for rewards> ---- As this would permit and nudge players to attack real players below hardest fight that is still far too weak to struggle with.
Hard opponent challenge?
If players did not spend so much time maximizing every single combat boost they could in the game, then there would be more 'challenge'. Just because players have unbalanced the game to favor themselves, does not mean that Inno needs to change anything. And even if Inno did change something to make it more 'challenging' - can easily wager that many players would immediately look for ways to counter it and reduce/eliminate any changes that Inno made - as such, it would be a waste of programmers time. Want change - change your City so you can have the challenge you require.
