Who buys Observer Ward

The share says how many games of a hero end with Observer Ward in the inventory, the win rate is that hero's win rate in exactly those games. A high share with an average win rate means the item is standard on the hero; a low share with a high win rate means it is a situational pick that works when it is needed.

When to buy it

Win rate by match length tells you in which kind of game the item pays off. Items that win short games are usually bought early and snowball; items that win long games are late-game purchases or things you buy when the game is already going well, so read the number as "games with this item at this length" rather than as advice to rush it.
