Free Value
Gaining damage or space uncontested because the enemy cannot fire back or use cooldowns.
When a caster says "that's free value," they mean a moment where the trade rate is completely asymmetric — profit at zero risk. It is the vocabulary that sums up the real worth of an off-angle or high ground in a single word. Where value is broad, meaning profit in general, free is a qualitatively stronger subset: the cost is zero. It appears when high ground, line of sight, and a CD differential all line up, and it is the most efficient state there is, cutting into the enemy's HP and the Ult differential at the same time.
When you can hit them one-sidedly from an angle they cannot return line of sight on. When all of the enemy's defensive CDs are down. When they are tunneled on the objective and the backline is exposed.
Stepping up thinking it is free when the line of sight is actually open, and getting killed for it. Getting comfortable in the free state, delaying the decision to push, and letting enemy CDs come back.
Off-angle
Solo position offset 60–120° from the main formation, enabling crossfire while taking minimal return fire.
High Ground
Elevated map position offering downward sightlines, cover, and safe retreat — the foundation of most setups.
Space
Physical control over the favorable parts of the map — high ground, routes, sightlines.
