PatchNotes

You run a two-character game for one season. The overall table says Ember is too strong, and your boss watches weekly active players. Make one balance change a week, decide whether to pull a dark lever, write the patch note. Then read what really happened: a reversal hidden in the averages, and a number that stopped measuring what you wanted.
