I wasn't referring to the player's roll on a ship, I was referring to the ship's roll in a team (ie disabler, brawler, hull stripper, long range support, finishing blow, scout, ect...).
This would be quite useful for people looking to step beyond the "Point guns at enemy, repeat" level of play.
I'd also like to see a guide to good ship pairings, as in "What goes good with a Junker?" or "What's the best ship for supporting a Mobula/Galleon?" or "What's a good 3v3 lineup, and what sort of guns should we all bring?" As a captain, I think it would be a great way to help improve intra-team cooperation to know what I can do to compliment my teammate(s) choice of ship.
Ship roles heavily depent on the weapon loadout of the ship.
As for the Junker question I guess you are talking about 2v2. In which case, yet again, depents. This is something you will have to work out with your ally.
Both the Galleon and the Junker are defensive ships which rely on their broadside weapons for their main firepower and can't point them at the enemy while engaging or disengaging, they are both relatively slow, though the Galleon boasts a great max speed
Ships like the Pyramidion and the Goldfish are attack ships, having their guns at the front, they can close or increase engagement distance while their main firepower on the enemy, both are durable and fast ships.
The Spire and the Mobula, while behaving mostly like the Pyramidion and the Goldfish, are limited to support roles (mind you, that doesn't mean they can't kill) due to their fragile nature and generaly not above average top speed.
The Squid is unique in the sense that it doesn't realy have much firepower, but is an incredibly agile ship, made for harassing your enemy and provide intel on their position as a scouting ship.
YET, even the Goldfish can be classified as support, depending on its main gun, Junker can either be a supporting sniper or a full on brawl ship, the Galleon need a good tackler to keep enemies off of it cause of it's horrible manuverability. There's lots of complications to make a guide for that unless you simply want a guide of what is the most effective meta at the moment.
