Restraint
Accrued at Warrior Job Level 77, Restraint: Enhances attack but weakens defense. But it cannot be utilized as an "always up" skill. Since the effect resets with each weapon skill, there's no good reason for 5 minutes of no utilization.

Here is my idea:

Restraint (Current)
Duration 300 Seconds
Recast 600 Seconds

Restraint (Proposed)
Duration 300 Seconds
Recast 300 Seconds
