No neutral-creep section in this official patch.
This collection contains official balance changes. It has no patch-aligned match sample, so pick rates, win rates and performance trends are not established.
Explore match evidence →These notes describe patch 7.27d. Later patches may change or remove these mechanics. Historical Facet and Innate sections are preserved as written, rather than presented as current hero rules.
Balance changes alone do not prove a win-rate effect. Compare a stated sample, role and time window before drawing a performance conclusion.
