The problem with this is that you would see a stupid amount of "micro" alliances, where a clan "splits up" into a half dozen clans just for strat. "Oh we are not the Fallen Alliance! The Fallane are just 20 members, those fellas over there are the Falling, and those guys are the Tripped. We just happen to be allied! Pure cooincidence."
atm you need to confirm if you want to trade between 2 factions, that has been implemented by pure willpower ;)
what i try to say, if you whant you can also implement that
1. factions cant have more then 50 members
2. Alliances and other diplomatic basic forms of relations
3. Costs of Trade
- trade between Factions without diplomatic relations have huge losses in that trade, like 70% loss of troops or gold
- NAP -50%
- alliances -40%
=> more clans have to engage on tehir own = more colors on the map = love it
