PVP is a total mess when it comes to balance.
It’s not just a matter of balancing weapons, but also armors and builds.
It needs a complete overhaul.
They need to focus on two main factors. Dps and dmg reduction. Then they need to be sure they can have at least two or three different playstyles that can match against each other. After that, they need to make sure weapons don’t break that balance.
A guy in light armor should deal small amounts of dmg fast and avoid dmg by rolling. A guy in heavy armor should deal big amounts of dmg slower and have the ability to endure heavy punishment. The second is a miserable fail.
The third option needs to stand between both.
But this needs to be carefully thought and tested by a team of skilled fighters over a few months, adjusting what there is to adjust until you get close to parity between the different playstyles.

If you get that right, pve will almost not need adjustment. I would have different setting for thralls for pve and pvp, though.
