Suggestion to get the game moving again
Kudos to the development team for constantly striving to add new wrinkles to keep the game fresh. The one area that's not been touched has been the fortresses. I think it would be a major improvement if you raised the fortress levels to 30 . keep the safe zone at level 8. Add safe zones at 12, 16, and 24 . This would get the strongest leagues already at level 20 to compete with each other once again. There are currently 100 leagues at level 8 . They would now strive to get to 12 and 16 etc. I leave it up to you to decide if and how much the knowledge should increase along with fortress levels , as well as the reequirements to upgrade to the new fortress levels.
What do you folks think ?
