If you nerf light (i personally dont care), you will dramatically destroy any resemblance of balance.
The issue is Muskets, with massive power, sitting out of range from any other class, with extreme accuracy. Its not an armor class issue. Musket can wear whatever they want, no one will attack them. Why? Because they are 200m away. And half the time you can hardly even identify where they are at.
Same goes for those bad bow players that just shoot through mid gates all game then flesche away once you’re within 200m. Having more ranged cover in OPR would solve so many issues with light armor being abused by uncontestable builds, but instead we get convoluted blanket nerfs supported by bad players with no concept of balance.
