I have a simple request: Make it so that if you take weapon/non damage over time (DoT) hits while on a ladder (sword, gun, blunderbomb, cannonball, etc) you cannot grab the ladder again for a few seconds.
Why do I ask this? Ladder re-grabbing spam. Normally if you take non DoT damage while climbing a ship's ladder you would let go and take knockback. However, because by default the key to grab and let go of the ladder are DIFFERENT (As an Xbox player for example, X let's you grab the ladder while B lets go of it) players can just spam the ladder grab key rapidly to avoid falling off and actually keep climbing upward regardless of taking damage, allowing them to get on the ship to do whatever for PvP, making countering it next to impossible save for if the hit kills the climber in question due to low health.
This defeats the entire point of ladder guarding when enemy players try to board. Before you tell me to use the blunderbomb and/or blunderbomb trap, no that sadly does not work despite the fact that's what it can be used for and I have tried. Not even the knockback created by a blunderbomb's explosion can stop a climber from spamming the key and keep going up to board you if they spam the key enough. I do not need to explain how this is completely unfair from a gameplay balance perspective. I can shoot or slash someone on the ladder and they can just bypass the knockback and get on my ship anyway to do whatever they want. While the Horn of Fair Winds and the Ashen Winds Skull could potentially counter this problem, these items aren't always available due to the specific requirements to obtain them. (Both are generally only obtained via World Events/Raid Voyages)
I normally don't seek out to engage in PvP nor am I some pro at it, but I have lost PvP clashes many times in large part because of people spamming/rapid tapping a button to bypass a counter tactic to the point it has gotten really annoying and frustrating to play. It should not be considered a 'skill issue' on my part when rapidly pressing a button like a quick time event in some other game can nullify trying to counter boarders so easily. I get it, it's a pirate game and people will PvP on the high seas and fight dirty. However this falls more along the lines of abusing/exploiting game mechanics to gain an unfair advantage.
