Caravans could have the option of using them as a "trojan horse" (a decoy) with several OP players hiding inside of it. So when and if the caravan would get destroyed, those players would pop out starting a massive PVP battle with players that came and attacked the caravan.
I can just imagine the shock players would go trough realising that they attacked the wrong caravan xD
This idea could already be thrown around somewhere in the forums, i just haven't seen it yet and it seems like a cool and fun idea. If someone already did post something similar, i apologize. I didn't want to steal the idea.
