The simplest way is to reset all weapons and armor values to the original values (tabletop?) when the game started. The player community can be notified ahead of time on a specific date of implementation. A moratorium period (a month?) will be held to observe effects and reactions, allowing for adjustments and changes in the next patch if it comes to be.
Weapons balancing is essentially a Gordian knot that keeps growing more spaghetti complicated until some drastic measure needs to be taken.
