This is different then lockdown, if you've played world of warcraft lockdown is just like AB and dueling is different. I propose a new room in haven where the grouping functions work just like the Advance training hall, just here you have the option to go solo and lock the party inviting who you like. Here you can choose to duel friends one on one in a plain 1v1 battle, If you've kept up with Whitelancer, there was the recent 1v1 Lockdown Tournament, OOO its obvious we want a way to duel 1 on 1 with our friends. Do I really have to break the forum rules for the devs to even read this?

We just want some way to duel people we know (without getting killed by someone who is in full PvP gear). It would also add another really fun addition to the game, when you're tired of always only doing clocks, blast network, and getting killed by someone who spent hundreds of thousands of crowns just for LD.
