Question: Is there anyway to change the loot tables/chances of getting the armor so the armor is more common?

[ClingooZ]

I tried using the config to change the spawn rates of the armor but it feels like it hasn't done anything. I'm using a MCSM modpack and it has this mod included, me and my friends were playing on a world with large biomes so structures tend to be farther apart. I would like the armor to be more common, like maybe 1/5 structures with chests (like buried treasure chests and desert temples) have armor but I dont know what to do to make it spawn more commonly.
