I guess nothing about big nations should be nerfed, since lots of players enjoy warmongering, but we need some buffs to small/medium homogeneous states to give an alternate gameplay.
I much prefer buffs to smaller nations rather then nerfs to larger nations, though they have to be balanced out so that buffs for smaller-medium nations dont overflow to larger nations.
That sentiment makes no sense. Power only matters in relation to others. A buff to smaller realms is equivalent to a nerf to large ones, if they are balanced similarly. I would prefer most balancing being done through nerfs at this point because it results in smaller numbers that are usually easier to track.
