How to read this site

What each section of Dota2Diff shows, how to read changes from the patch notes, and what the badges and percentages mean.

A change line

• The site takes Valve's official notes and splits every change into “before → after”. Numbers separated by slashes are per ability level: 20/30/40 means 20 at level one, 30 at level two and 40 at level three.
• The verdict badge shows whether a hero or ability got stronger: “Buff”, “Nerf”, “Mixed” (some parts better, some worse) or “Not rated” when the text does not tell.

Sections

• Compare — every change of a hero or item between any two patches, a stronger/weaker verdict and the history of every value.
• Patch overview — who changed in a patch and in which direction.
• My heroes — changes to your heroes since the patch you last played.
• Hero vs hero — stats and abilities of two heroes side by side.
• Strategies — best teammates, counters and popular items from recent public matches.
• Team builder — a five-hero lineup for a game plan.
