Is just a consequence, not a cause.
I mean... they chose to do so... hence why complain that it could be even easier ?
After all, ship knowledge is not locked behind anything. Is just tied to using the ship and everyone can do that.
- get ship, sail ship, fight with ship, sink or get sunk, get another, sail and fight more -
Was the best advice i was given by an opponent in this game.
They were right. Eventually the slots get unlocked if the prevailing objective is the hunt, the port battle, the escort... in sum, get into a fight.
PvE has its own rhythm and i'm glad it does. It fills in the gaps and gives a large sect of game population the "combat int he age of sail" feeling.
But... like many things in games... things start to look less green when we game the game and rinse and repeat because... it makes things easier.
