These games are meant to give the illusion of plausibly simulating history, and when you can gain a Kingdom by pressing a random-nowhere's claim just because you granted him a barony, that's not achieved.
I agree, because i wouldn't even have to give that barony for him to agree with the whole deal...
There's a consistent pattern in Paradox patching of loopholes being closed and the game becoming a bit harder as a result, and thats fine. Especially in a case like this where, even with ZERO modding skills, if you like the current system, you can simply backup the current /common/cb_types.txt file and be certain to be able to overwrite any future changes using the current file.
But won't that risk some incompatibilities? I don't have time to research how the files interact with each other. But saving a file from a previous version and use it seems risky. Would be real fine if it is completely compatible.
