A little change can make a big difference in terms of balance. It’s what Albion Online did with its latest patch; all that’s really been changed is that trade mission packages have had their weight increased by around 400 kg. The thing is that a heavier package means using different pack animals to transport it, which in turn means not being able to rely upon using mounts with more survivability… and, in turn, it means that these trade missions become a lot riskier. See? Balance from a little change!
The patch also contains some other balance tweaks for faction leaders, as well as updating the marketplace UI with several quality-of-life features and fixing several bugs along the way. But the biggest change for the patch is, well, a little change that should make things harder for a lot of players who will rely on more vulnerable mounts now, which encourages more back-and-forth warfare, which is exactly the point.
