No matter how much you try to cheapen the portal, it won't get any better; only a complete overhaul will help, for example, so that you can fly to any city. And diplomacy on creatures of level 1 and 2 is complete nonsense – everyone will play with diplomacy and gather a bunch of units to destroy everything.
And the problem isn't a lack of desire to improve the game. The problem is that the method you suggested is useless and even seems like trolling.
