This is something I have mentioned before in other threads but never elaborated in how I see it playing out. We see a lot of topics from players frustrated at the difficulty of AI encounters (mostly new players) and then there are those of us who see them as more of a nuisance than a challenge now after all the nerfs and such.
While I do think it can be very bad RNG to encounter multiple AI at once (and that's a separate topic maybe), fighting any one of them alone is basically going through the motions for a lot of experienced players.
So I suggest the difficulty of these encounters be scaled depending on your crew's average level.
How it works...
Firstly, the game assigns your pirate a "level" based on the average of your top 3 faction levels. For PLs, this is going to be 50 regardless.
Next it looks at the ship size and crew number. It assigns a "weighted" value of 25 to each empty crew slot, plus one additional weighted value of 25.
30 is the current difficulty of encounters on that particular ship type and it scales up or down from there.
This means the max difficulty value is 45 for a crew of PLs. For an absolute newbie (hypothetically at 0), sailing solo, it's rounded at 17. Obviously, they could make the encounter easier for themselves by crewing up but I suggest the lowest possible threshold be set to 20 for this reason.
So, in practice, the scale actually goes from 20 to 45. Again, 30 is the difficulty of encounters as they currently stand. How easy 20 is and how difficult 45 is, is something that would need to be tested and would likely not be a linear scale.
The first point at which you will encounter the current difficulty of AI when solo slooping is when your level is 40. A PL sailing solo on a sloop would get AI with a difficulty of 33 - a slight increase from current difficulty.
But, in theory, this should make encounters less difficult for inexperienced players whilst also increasing it and giving more of a challenge to experienced pirates.
Obviously, I am open to suggestions on how to improve these calculations, but I really do think the scaling of AI difficulty needs improvement beyond just ship size.
(P.S. Yes, loot drop values from the encounters should scale accordingly too)
