I apologize if this sounds harsh, but if you make a whole post centered around one assumption, maybe you should research that assumption first.
It’s true that people didn’t complain about the balance of mounted combat immediately after they were released. These things take some time. But it’s not true that they waited 7 months to start complaining. There are complaints dating back to March. Maybe even earlier, but I did only a cursory search in the General Discussion forum and that’s the earliest complaint I could find in the 5 minutes I dedicated to it.
Now that this was shown to be false, maybe we can transform the topic into a discussion about mounted combat balance
