I tested with a friend, 10-vs-10, 10 full length greatswords vs 10 full length white lions, each with 3 chevrons so they cost 900 each, equal to the greatswords.
The win count was 5-5.
Greatswords have 22% more HP, white lions have 30% missile resist and +5 speed and forest strider.
White lions have martial prowess disadvantage. Greatswords have bonus vs infantry disadvantage.
I don't think this is how these units should be stacking up, and I don't consider greatswords to be terrible units. They're medium quality, but with their bonus vs infantry they can reliably punch above their weight in these kind of head to heads.
Simply put, the buff to white lions was a little too much and it synergizes too well with martial prowess.
Recomment -2MD, +2CB to undo half of the buff they got. Which was to keep up with silverins anyway, who got the nerf they needed.
Or you could buff greatswords, chaos warriors GW, longbeards GW, and any other "underperforming" units in this class by the equivalent. But I don't think they're the issue.
