Instead of landings, every clan with some minimum number of members should just get a "home" territory by default as part of being a clan.
- Home territory might have basic income or resources but hardly anything.
- Home territory can be raided by other clans for minimal reward or just braggin rights.
- No two home territories next to each other. Someone break out the voronoi algorithm...
- "no man's" territories between homes are up for grabs to fight over.
- extra owned territories give increasingly more (geometric, arithmetic?) resources including gold income.
This would make it easier for lots of clans to get involved in clan wars. Maybe even dump the whole Strongholds thing.
