Did they change the cost of improving kill cards? 500$ for rank 2 is a bit expensive.
I'm pretty sure it used to be $50. Leave it to R* to say they fixed something only to screw up something else in the process.
As much as I love RDR2, R* is a predatory company and one of the worst in the industry when it comes to respecting it's playerbase. They don't give two shits, as long as they get money out of you.
