My cellphone also charges to full faster than an electric car from the same power outlet, should they undo the healing reduction change? Note that I agree with the reduced healing on smaller ships. If you want a fluffy explanation then the Plasma Web covers the shields/hull and starts burning. More surface covered = more damage. There you go.
The thing you are not understanding is, using your own example: Yes, it has more surface to be covered, but why should an interceptor be able to carry a device to engulf the entire surface? The more surface also means that for covering it up it would use more energy, if the energy spec is maintained, as the interceptor doesnt get more powerfull when using it on a frig, then the same web would have to stretch to a bigger surface, thus reducing it’s effect instead of increasing it. It would be the same comparison if you took 1g of butter to cover up a slice of bread, and using the same amount to cover a tennis square. The amount of butter would be the same, but the surface is bigger, but does the area gets more buttered on the tennis square? No, so why should a fixed power weapon do more dammage just because it has to spread into bigger surface? It is just not logical.
