as i think from start, the game has no balance in ptw and high lvl content.
after a week of merged servers map looks like that
in a 1d6h all light blue and green merge to dark Blue
+ some of purple and orange (i want to believe less than 10%) wil go to yellow or Dark blue...
in another 5-7 days yellow with dark blue destroy rest of purple and Orange
they mass migrate to yellow or Dark Blue (i think most of DB)
and in another 3-6 days one kingdom kill other kingdom (i think BD kill Yellow)
Game over in 2 weeks
