Hello i have an idea for borders. You see when you filled all you borders with 8s theres a lot of tropps with no borders and smaller numbers surrounded by 8s.
Since its borders and your borders are filled the computer doesnt go with border and the rest is random. But this means that if the enemy break throug your 8s youmaybe have like 1s r 3s or weaker regions there. So my idea is when borders are filled instead of random they should fill out the troops right behind the borders. This way you will make like 2 big walls in stead of 1 and saves a lot of time. You say it might make it too easy. But its hard to et to this situation and if you have many enemies and play like attrition that shouldnt matter much. And better defences makes it easier to reconnect regions and produce more units. Of course this could be an option for borders. Borders defence .You choose between that and normal borders.
