Again, absolutely thrilled to see something I've called for on here in the patch notes. In this case, the weak claims to the liege for losing folks to independence. It was abuse-able, and the AI was essentially suicidal to participate in such factions. No more easy strong claims to the gamey folks, and another glorious step towards the death of snowball blobbing! Much love, Paradox.
Though the "more aggressive towards revolters from external powers" bit makes me nervous. Hopefully, that won't result in one blobs breaking up just perpetually feeding other blobs. But I'm a weirdo that enjoys seeing smaller states survive in some corners of Europe.
Oh, and all those notes on dynasty fixes... but no mention of House of Argyll in the Isles, who are a quick trip to "game over" without editting the data, as the Earl's firstborn, non-bastard son is of a different dynasty. Its a simple fix for the player, but until Cadet Branches get included and allow you to continue along their lines, the current set-up isn't a friendly one to potentially new, ignorant players thinking a Scottish count could be a fun romp (which it totally is!).
