So the main problems people are stating is disparity between size of alliances and Alliances making alliances between each other and owning the map.
So how about we force the change. Instead of each alliance standing on their own they get migrated and join forces with another alliances for the duration of the war… the migration would mix tiers together
example; a top 10 combined with a top 20 (up to 120 kings). its random so you cant pick allies you might have to work with your enemies
This way the lower kings have other kings they can beat and attack. there is a lower Skull to dis-incentivise high Kings grinding on lower kings.
it breaks up alliances working together and makes the war more interesting.
if 5-10 kings don’t attack it doesn’t matter so much because out of 120 it makes not as big a difference. atm if you don’t get all your kings getting 3 good scores you might loose
Make the maps bigger. so there are more opponents on one map so less likely to have allies and if allies are on map they will want to keep their kings rather then moving kings about between alliances to un balance wars
