1.5k armor

Historically, the phrase "1.5k armor" referred to a set of armor that cost 1.5 platinum per piece to craft. These sets were crafted beginning in Droknar's Forge, and had the best stats among their own type of armor. However, this phrase is now obsolete when integrated bonuses in Prophecies and Factions armor were replaced as the insignia system introduced in Nightfall. Armor which previously cost 1.5k to craft now cost 1k, as the player must purchase insignias for each piece of armor. The phrase survives through habitual use despite being technically obsolete.
