matchmaking only really works well with a large multiplayer pop tbh, im not sure how big bannerlords is but wbmm sucked any fun out of warband for me, you need enough players so you dont get put in with the rage babies every game :p
Personally i really dislike skirmish so its a long wait for battle modes and community mods like crpg/mercs so i can pick actual items, hopefully not so long that i just give up and never reopen the game lol
