Agreed, as they should have jails where they can get locked up in as most of the time when people knew they would get caught by the stronger players. Which right now there are not players who are willing to stop them and do that as they can also die in one shot to them most of the time. But this is an issue with sword arts being overly oppressive to damage dealing comps when they also have aoe to wipe out multiple people when in a real battle the 3 probably would wipe them off with no problem.

I know Opal's been developing the Laughing Coffin guild on her own, but that's not necessarily a site-wide plot. As for the jail, I'm kind of iffy on that. The only ways that I can imagine that being done would be to either force them to use a teleportation crystal that takes them to the jail, which might be a bit on the godmode side of things, or to have them physically go to the jail itself which would be impossible for actual orange players.

As for the actual mechanical problems with PvP, I think a good way to go about it might be increasing base HP/HP per level a bit so that most sword arts aren't a one hit kill (and increasing mob damage as well) and maybe making AoE sword arts only work on monsters. Thoughts?

It doesn't have to be a plot per se, but people seeking justice should be able to do something... And just 'attacking' to know avail won't be enough... But I understand its a grey area.  
I think AoE only for mobs is a good plan. Increasing HP seems like a good plan too. Some bonuses on evasion would be nice, so that one hitting becomes more difficult (also evasion is much weaker compared to mit early game)
