With Hardened Adrenaline Rush, 10 seconds of time for you is 5 seconds of time for the enemy. However, DPS is only relevant when you are using weapons with a high rate of fire, and it is relative to the time passing for YOU, not the enemy. Heightened: DPS x 0.3 time x 240% damage = 72% DPS.Hardened: DPS x 0.5 time x 200% damage = 100% DPS.The damage-per-second is actually higher with Hardened Adrenaline Rush: If you play conservatively to avoid damage AND prefer to place single high-damage shots, then go for Heightened Adrenaline Rush. If you play very aggressively and are willing to fight when injured, go for Hardened and the damage reduction. The difference between Hardened Adrenaline Rush and Heightened Adrenaline Rush on rank 4 is a hard choice. You want to maximize the duration of this so you do not have to constantly invoke it.

Also, there are missions where you face endless waves of enemies until you reach certain invisible checkpoints or accomplish certain goals. There are ways to stop health regeneration, but if enemies are able to raise their protections again, that can be a huge drain on ammo.

You therefore have to be good at shooting, and watch out for enemies that can regenerate their protections or health. Soldiers are self-sufficient builds IF they have enough ammo.
