Now we all have played on sloops, alone or in a pair does not matter, but if you play a sloop, and you get panicked from seeing a brig or a galleon, you obviously do not know how to play a sloop and complain about that bigger ships are OP and that sloops need a buff.
Sloops can tank an incredible amount of damage, is incredibly versatile and can escape any bigger ship when against the wind. The most insane combat is 1 sloop vs another sloop. As sloops do not need a lot of fixing, and if the helmsman knows what he is doing, a sloop could easily sink even a galleon with a full, experienced crew.
If you want to become an experienced solo-slooper, practise with lone skellyships or ghost fleet voyages to build a good way to manage to steer your ship and shoot your cannons at once without getting stressed. Or if you want to become an awesome double sloop crew like me and my friend Samy, I recommend for you to do the ghost voyages or skeleton fleets to learn how to manoeuvre your sloop in the best way. One of you should be awesome when it comes to steering the ship, evading, Anker-turning at the right moment, sail managing, that should be one of you. The other should always be the cannoneer. Shooting at other ships, not over to. Getting masts down and aiming for the cannons to not give the bigger ships a chance of retaliation.
Sentence of the day: The sloop does not suck against bigger ships, you just don't know how to use it properly.
