Why would you even create Poland-Lithuania as Poland?

[modern bobcat]

As far as I know, PLC grants no nation unique advancements (when playing as Poland) nor any positive modifiers.
I suggest that forming PLC should grant you some fun benefits (bonus to cultural capacity, and maybe advancements which aren't available to Poland otherwise) for as I see it now, all it does is giving you cool flag, random civil wars, and nobles which demand a privilege that makes you suffer for your entire game and is basically impossible to remove or failure to comply, which makes you suffer for like 50 years or so. (everything indicates these events are not Poland specific but PLC specific, I didn't double check though )
I could even argue that forming PLC makes your game harder and more annoying, and you are better off just not forming PLC at all.
Thank you in advance to anyone reading this.

PS.
I forgot to mention that forming PLC grants a random privilege to your nobles. for like no reason at all. I even wonder if that's just a bug or an intended mechanic (it could just be me tho)

When I formed the PLC it gave no privilege to the nobles, (Golden Liberties)

This goes for most formable nations, theres alot of formables without any benefits; the PLC isnt the only one and this will most likely only get fixed through DLCs

[smoky knoll]

isnt the golden liberty paradoxically a good privelege in the game?

Hell no
