What the title says. I just started a new warband and I'm only getting exp for kills. Has I been so long since I started a new one that I've forgotten what it's like in the beginning?
Or is it something new I've missed? Or a bug?
That happens when your opponent is underdog to you. Underdog is calculated based on a % ratio of the warband ratings, so at lower values the warband ratings have to be extremely close to award you experience points, and the system is trying to not match you against the same warband over and over, so it often misses the window where neither team is underdog, until you get a bit further along.
My experience has been that it gets better at finding "fair" matches, meaning neither team is underdog, around warband rating 80 to 100.
