Noe noe noe……. You are not even close to end game my friend. If you want a real challenge you need to break contracts with larger city factions to the point they will attack you. Larger cities have huge militias that are heavily armed and have captains. This will also allow you to attack caravans leaving that city. Even with bros at lvl 10, larger militias will easily wipe your team if you are not properly prepared.
