I believe there are really two areas to touch on when it comes to re-balancing the meta-ship.
Now, the obvious imbalance is the speed of the Brig. It's absurdly fast in pretty much every wind condition regardless of how wonky their sails are. You always have to fight a brig on the brig's terms. They control the resets, the engagements, and pretty much all aspects of a fight because of their speed. I've put a thread out in the past about generally rebalancing the speed of all the ships (read about it here), and I stand by the need for that.
The second re-balancing area has to do with pressure, and this area has really only become a problem since they got rid of the popcorning (which they seemingly only did because of people whining in Brig v Brig hourglass battles). The underlying issue is hole placements on the brig. It has 18 holes, just like the sloop (Sloop 18, Brig 18, Galleon 24). The problem is that the middle ~50% of the lengthy Brig, where the cannons are, only has 4 holes (2 per side). Taking a brig's masts down has become a pointless endeavor unless it's a bad crew. The halfway competent Brig crews have seemingly all adopted the rotate and turret method when de-masted because one person can easily out-bilge the minimal hole locations where pressure needs to be applied. On top of that, since they got rid of the popcorning, you can't even keep people off cannons anymore, so they can always shoot back while you try to apply pressure.
So, the fix would be to add additional hole locations in the middle of the ship (thinking 1x per side, maybe 2 on one side and 1 on the other to give them a "strong side" like the sloop has and to put their hole count right between the sloop and the galleon)...or bring back popcorning. I'd vote for more middle-ship hole locations because of how annoying popcorning is on pretty much any ship, but either of those would work to rebalance the general tankyness of the meta-ship.
