Currently there are several weapons in the game for various classes that have astounding range, making long range frigates nearly obsolete on the battlefield. I would recommend a quick buff to their special module and primary weapon max range to adapt to this ever-changing battlefield.
Disintegrators are already hard to use at great range, but should still be useful for pushing destroyers under cover. I would recommend that the Disintegrator range be changed to 20km.
Guided Torpedoes have always been at a major disadvantage due to their lower range, made even more apparent in modern battles. I would recommend that the Guided Torpedo range be changed to 15km.
