I have put $50 into the game, and deciding how many longer will play. In my opinion, the game would be more effective and reasonable if invader and ghosts of different levels were mixed throughout the map. In the kingdom and clan i am in, their is low activity, and if i also have to spend 5 to 10 minutes round trip per attack to hit these, i will get old fast, especially if a closer town delivers the final strike.

Option 2, Do them randomly by percentage (%) throughout the map. For Example: In Current area with ONLY LEVEL 1, change to: 40% Level 1 invaders and ghosts; then scale down percentage; example: 25% level 2, 15% level 3, 10 % level 4, 7% level 5, and 3% level 6.

In current level 5 and/or 6 only, do opposite. Thus, still would be difficultly levels on map, but allow reasonable and realistic attacks throughout map.
