The title says the main point
I will be focusing on Open World PvP, but this also happens on Hourglass PvP.
The game is way to defensive, is really easy to repair your ship, and since the addition of the supply crate for 5k gold, the game became mainly a supply battle between crews of same level.
Also, from a solo perspective, going agaisnt any bigger crew, is a absolute pain, since boarding to stop repairs needs to be REALLY precise, you need to properly spiral your ship, fully repair him, and kill the enemy crew at least twice and hope they don't get a single shot onto your ship while you are there. Thats a lot for a single player.
Also, for sloop vs sloop, since the mast now takes two chainshots, it became a battle of: sail away, go far, reset your ship (fully repair), come back and try again.
I know sinking in SoT is something big and can take anyone out of the session, but the battles should definetly be faster.
So here is some ideas:
After receiving a ton of damage on the same spot, you receive a hole that you can only FULLY repair (You repair, then after a while the hole break alone) in the shipwright.
Make repairs take more time.
I know solo should be the hard mode, but duo sloop should be fair agaisnt any bigger crew, so maybe make the hulls of the brig slightly weaker (only holes T2 above), and galleon have way weaker hulls (Only holes T3 above).
Make wood slightly rarer
For sinking not be that frustant, the place where you spawn is closer from where you sunk (In comparison to todays game).
I know PvP always was a kind of waste of time, but things are getting worse in recent times. Those are just some ideas, not the best, but some.
