Same reason I won't be going back to defend my point either haha. I mean, we could probably use the advanced search tool to look for "10%" by username "Callum" in the "The Proving Grounds - Beta Discussion" board, but who has time for that.
And look, I know we are on the same page in that we all want MP to be great, and I know there are many issues with Bannerlord's MP right now, including what you highlighted with new players being steamrolled by experienced premades. Believe me when I say I'm very much of the, "give us ranked MM ASAP" crowd. However, unfortunately, we have limited resources and have to prioritise our work. And while it might seem as simple as just offloading the work to an outside source, it is actually much, much more complicated than that.
