- Dodge any guns, provided the gun user is anything short of blackout drunk.
Sword vs sword fights take a lot of skill; you can't just mash attack, because whoever started mashing first will have priority and be the only one to get any hits in (and you're not always going to be first). You have to take your opponent's swings into your block, or dodge to make them miss, in order to retaliate. But you'll then also have to account for them trying to do the same to you, but if you create even more space they might pull out their gun to get a cheeky shot in on you. The sword vs sword meta is deep, and it's disappointing that you're trying to write it off as if it doesn't take any skill.
Sword vs gun fights take a lot of skill; in the open water you're dead, and on a ship or land you have to use hard cover to avoid getting shot until you're close enough to get any swings in. Even then, the gunner might pull out a blunderbuss to deal with you at close range, and even if they miss a shot before you reach them, they can reload before you can get your 4th swing in. Truly a difficult situation in any case, and it's disappointing that you're looking at it from such a shallow angle.
Gun vs sword fights take a lot of skill; in the open water it's easy to hit players, though you only have a few shots before they reach you, and you can't really escape the blender at that point. If your aim isn't on point, or you're not carrying a blunderbuss, you're dead. In the tight areas of ships, which swords are intended for, it's even more difficult to keep your distance while getting 2 hits in.
Gun vs gun fights take a lot of skill; regardless of the situation, it comes down to who can aim faster and more accurately, and in some cases the fight can even be won by who has better control (or denial) of the nearest ammo box.
I'd like to hear (and correct) any further questions you have on this subject.
