What is "Denial"?

Denial measures your ability to deny vision, taking into account how much vision your opponents actually place. 

• This score evaluates your ward clearing contribution in relation to the total amount of wards that your enemies placed.
• To increase this, simply clear more often and more efficiently using Red Trinket, Duskblade, Scryer’s Bloom, or Control Wards.
• If you tend to forget to use these items or use them at poor timings, you may have a lower score here than your peers.
• If you're an ace at predicting when and where your opponents ward, you'll tend to have a higher score than your peers.
