Great thread and excellent dialog. Here are my thoughts.
Sounds like this is an issue less about botting and more about "anti-fun" actions of a few players. I think just about every player would be ok with bots...provided they were not used in a way that excessively ruins the game for others.
This reminds me of some advice I was given by someone I really appreciate. "Don't be that guy."
We have all known someone...or at times been...THAT guy. The guy that can't take a hint, the guy that over stays his welcome, that always orders the most expensive item on the menu EVERY time someone else is buying, the guy that crosses the line.
What we are dealing with is a small group of players, who are THAT guy.
Fortunately, most reasonable people are willing to listen and change behavior if someone can point out when the line has been crossed. "Hey, that was a pretty crappy thing you just did. We (meaning you) should probably fix it."
Unfortunately, we as players have not done a very good job of addressing our own issues. I'm just a guilty as the next person for not speaking up when I KNOW another player is being THAT guy. Sure, some of this crappy "win by ruin" attitude will exist at some level or another, but we need to change the way we handle it.
I'm calling out the clan leaders in particular here. You are quick to recruit one of these highly explosive players when the war is close and battles could go one way or another pretty easily. But once you have unleashed the hounds, you do very little to reign them back in before they become THAT guy.
I don't often see leaders take the high road and reprimand someone for crossing the line. And we ALL know when that line has been crossed. We aren't 15 year old kids mudding from the high school computer lab anymore. I guess what I'm trying to say is, have some common decency. Show a little respect among enemies, and for heavens sake DO something about problem players in your clan before Hoss or anyone else has to start deleting everyone.
Apart from that, I think a 5 level spread for PK would be a good idea. You cannot attack or be attacked by someone unless you are within 5 levels of each other.
Also, adding a "player problem" report function just like the typo, idea, and bug function would be good. Except rather than going to an immort, the problem gets sent to the clan leader. I would hope clan leaders would want to know when their members are being THAT guy.
