Flat is not the opposite of Bonus. Flat just refers to a non-percentage reduction.

Something that affects Bonus Armor doesn't affect their base stats; while something that affects Total Armor will affect their base stats.

Let's say a champion has 200 Armor (50 base and 150 from items/abilities/runes).
 * 20 Flat effectively reduces their armor to 180.
 * 40% Total effectively reduces their armor to 120. (Live GP)
 * 60% Bonus effectively reduces their armor to 110. (PBE GP)
