The point is that skill SHOULD be over equipment. If equipment allows to "press x to win", nerfs/buffs really are necessary. Like it's been said here for a 100 times, all ships should have both strengths and weaknesses - if a large ship has huge guns, then it should steer like a cow, a small quick ship's weapons and armor should suck, etc-etc-etc.
Yes, perhaps, but in the same class? If a Viper is sufficient to just kill everything else then that doesn't seem right to me. I can see why a group of small fighters would take on a bigger fish but I can't see why game logic is served by making every ship of every class essentially balance for combat. To me, that is not interesting. Medium ship combat and large ship combat should be things in their own right; instead they're owned by a Herbert in a single viper.
