The only reasonable solution is to continue the fight again multiaccounts and multi farming. All other hard, mechanical limitations would cause even more disagreements.
- First of all, the rules should change and friendly farming shouldn't be legal.
- For a member who leaves a kingdom (except when he is kicked out and not reinstated), the rules for looting kingdom members for 24 hours must apply.
- There should be a limit to plundering wing-kingdoms and kingdoms with diplomacy in between.
Friendly farming would have to get a solid definition, written somewhere in the game rules. Is being a farm or low activity player punishable?
How would you want to punish low activity players(farms)?
No friendly attacks would also make treasures hidding and inside kingdom ress transfers using troops impossible. It could also make it impossible to catapult villages settled inside kingdom territory that are either hostile, or settled in the wrong place.
The lack of ability to farm freshly kicked players doesn't forbid everyone else on the server to farm them anytime they want, why would it limit only a certain group of people? The NAP is the same thing. Alliance(confederation) prevents from conquering a village.
Perhaps a mechanism that would make it impossible to invite, kick and invite again various accounts anytime you want would help with the situation? It won't limit the multi farming from the accounts outside of the kingdom, but it could help with the kick, farm, invite again multi strategy a lot. Maybe a cooldown saying that you can't join again to the same kingdom you got kicked from for maybe 24hrs?
The goal here is not to limit every player on the map with more limitations, but to ban multiaccounts. Some people suggest that implementing some of the old rules from the older Travian or Travian Legends could help to solve the situation, but this is Travian Kingdoms and it often plays very differently.
Some Kingdoms have a dedicated scouter or WW builder, attacker who always goes first and dies. Is that playing for the greater benefit of the account or the entire kingdom?
