How to add a teams element without coding teams

[Aenor]

Have an NPC in each city that allows you to join guild "Protectors of Starting City X." The thing that teams provided was context so that it was us versus them and not just a purposeless gank fest. Those who want to gank don't have to join the guild.

But those that do join the guild will get to enjoy a sense of civic pride in their home city without the devs having to code teams or deal with the ensuing issues and exploits. Just make it so that if someone kills a member of guild X they can't subsequently join the guild to avoid retribution.

This is especially helpful in drawing new players to the server who don't have a guild waiting for them. Idiots who are going to flame this idea, this means more targets.
