Maybe replace some of the 2h weapons with crappy weapons such as knives, meat cleavers, sickles, throwing stars, small maces etc? I've seen almost only 2h weapons, usually large axes and some polearms and only few 1h.
Also it would be nice if there is only one weapon at one place, otherwise whole groups will arm themselves in just a single house/cave.
And there was a bug in which I was teleported out of the cave before the match started, that happened when I was standing at the gate and we all got our winter uniforms. Some more smart troll could use this for a nice journey.
