+1 for the principle of protecting weaker players from being plundered.
Exactly how to do this I don't know; I tried offering a couple of suggestions, in this and in another thread, but they were turned down. My first suggestion was to create a world where plundering was disabled, but I was told that the devs do not want any differences between worlds. My second suggestion was to use coloured flags, but that idea went west too. So I'm a bit out of ideas, and I'm a bit afraid that any proposal in this forum would end up being poo-pooed if it didn't favour plunderers.
Quoting my own post in another thread, I have a problem with all players who enjoy plundering weaker players. If it happens to me, I just stop playing in that world and disconnect the roads. But I've seen good people leave the game altogether because of it.
The fact is, at least 95% of players are decent and generous, and don't plunder. In fact, I play in 10 worlds, and I'm very rarely in a neighbourhood with a plunder problem - but I know people who have been. It takes just 3 plunderers out of 75 players in one neighbourhood to spoil the game for the other 72. How does that make sense?
I enjoy battle, and have often topped the tournaments, but I never plunder. I admit sometimes it's been tempting, when you see lots of nice goods buildings ripe for the picking. But I know it's going to upset a real person playing the game somewhere in the world, so I don't touch their stuff. Unless of course I or my guild mates have been plundered - then I return the favour.
I understand people might not want moral issues brought up, but what difference is there between plundering a weaker player and bullying a weaker person? There is a real person behind the city that's plundered; it's not an NPC.
So of course I'd like to see a system set up that protects weaker players from being plundered. Ideally, I'd like to see a world where those who like plundering can just plunder each other... but plunderers wouldn't like that, because it's much easier to plunder weaker people. And as I said, there are few plunderers in the game, so plundering neighbourhood would be rather few and/or small.
It seems to me that 95% of players are there to provide entertainment for the few plunderers, and it also seems to me that most of the people on this forum are rather keen on plundering. Which is strange, and I don't quite understand it, because in the game the vast majority of people I meet hate plundering, yet in this forum it's the other way round.
