Biggest issue is with bullies. I played for about six hours today 2 man sloop we avoided other players and docked at an Outpost to sell our loot. Then after we're docked we get attacked by a 4 man team. I was in the crows news and scouted all around no ships, then right after I hop off the boat , not 20 seconds later one guy is on my ship and killed my teammate. The ship was sunk in less than a minute and when I spawned back in after loading for a full minute ( on an Xbox 1X) I am at an Outpost on the otherside of the map with no chance of catching my stuff before it's all turned in.
Biggest issue is I was not engaged with a ship nor was I being chased yet this ship server hops or spawns in at my Outpost and I'm unable to defend myself. You will constantly run into expirenced players attacking new players. There is a pirate code posted in the tavern but it means nothing, one code is that disputes are to be settled upon the wave yet I was attacked after being docked at an Outpost.
The game lags constantly and once after a server switch that you cannot control my friend and I we not able to enter our ship we would just fall through it into the water and because of this we lost all of our loot and progress.
I can not recommend this game to anyone with there being no way enforcing the "pirate code"
