I would like to see the introduction of a 'duel' window, which would be somewhat like the the team window.
After inviting somebody to duel, he would then show up in your 'duel team' (maybe more than two people could be in it at once), and you would be able to engage in combat with him, and him with you, in 75% suppression field or lower, regardless of level or alignment.
There would have to be a duel-exit-waiting-period of a minute or 30 seconds or so to guard against rapid-exit exploitation.
This would appease many of those disappointed when the rules relating to teaming and PvP changed so low levels could no longer fight high levels. That change was needed to simplify combat and make it more fair, but it had the downside of preventing friends from fighting each other for testing purposes. This would be allowed again. The allowing of fighting in 75% is only a secondary suggestion, because fighting with large differences in level before was only possible in PvP areas, though being allowed to duel in 75% would be more convenient, especially for RP purposes. My primary request is that the ability to fight with high level differences on a mutual consent basis be restored.
I see few hitches with implementing this, but I'm not a dev so I couldn't know for sure.
Help me out with your shared thoughts
