I, as a player who plays this game mainly for the sailing and naval gameplay would like to put my two cents in to this argument.
I wholeheartedly agree with the original post. This bothered me to no end in POTCO, and due to what seems like quieter waters (less AI ships) it really gets under my skin in this game. In POTCO, it had been proven, whoever got the last shot in, got the "prime" loot. I believe they may have changed it to, whoever did the most damage, however, in this game its hard to tell, and it really doesn't matter. I work extremely hard, to sink the ships I do, because I'm trying to increase my sailing level. I know I personally, make an effort to keep myself, my ship, and my crew, from firing upon another player who is in combat, with another ship, so that we don't negatively impact their loot, or rep. This subject wouldn't annoy as much, if I didn't fall victim to it, Every. Single. Time. I. Sail. I mean, I cannot go out to sea anymore, no matter what the time of day is, without having my ships stolen from me. I've even had it to where, people will FOLLOW ME, and attack the ships I attack, and many times, they're higher class ships than my own. I'm only on a standard Brig, how on earth do I hold my ground, when I've dropped a ships health down half, taken out its sails (all on my own, which takes 10-15 minutes sometimes) and someone in a war ship, swoops in and steals my work. I understand you can't make everything fair, but this is, in my opinion, a very real issue. It disappoints me to see this, especially when sailing is the biggest (and honestly, almost the only) reason I play this game now, and back in the day. Please don't give me the usual "go play another game, nobody is forcing you to stay" because in my eyes, there aren't other games like this, in the regard to open world, naval gameplay. There are some that are similar, but not the same.
Long story short, this bothers me to no end, and I hope in the future we can either all get along, or something can be done in-game, to aid in solving the problem.
