I think (id have to do alot of back checking) a while back they doubled the cost of bombs, reduced the amount of brimstonenharvest rate, lessoned the bombs damage (burn damage dedinately). So it costsvalot mor etonraid. And another missed point is many dont want to raid empty bases. BVs have invreased once people found out how cheap alts are. So players are offlining just to destroy, not actually raid. that getsvold really fast.
