I agree with both Lucifer and Sombody1212, and I do not think nerfing the meson is needed.
In its current state, the only meaningful way of using mesons, is mounting them on fighters and have a swarm of them. This is largely due to mesons only do 1 point of damage regardless of their size and tech. With such a meson fighter swarm, they can only start to deal damage after wading through AMM/AFM fire, possible interceptors and area PD/anti fighter beam weapons. As Lucifier pointed out, they are easily countered if the opposing has competent anti fighter capabilities. Without anti fighter defense, a swarm of microwave fighters or missile fighters can also wreck havoc on such a fleet.
From a broad point of view, since mesons are almost exclusively used on fighters to be effective, some changes in C# are already indirectly nerfing them. For example, the small engines generally use more fuel in C#; the nerfing in sensor range with large resolutions will make small resolution sensors more efficient thus fighters may lose their 'stealthness'; the failure rate on weapons also penalizes fighters more than other ship types; the missile engine/E-war change makes smaller missiles less capable against ECM equipped ships; and the missile launch detection change makes torpedoes largely obsolete. With all these changes, I don't think more nerf on meson will make fighters in a better situation.
