I would like to report this bug with the new named Backpack "Hermano" which has the Perfect Overclock Talent.
Based on the talent description, skills on cooldown should receive a 60% CD Reduction while the player or their allies are in proximity of a deployed Skill.
The normal talent on a non named Backpack grants a 20% reduction only.
However, at present, both the Perfect and Normal Talent are providing the same 20% Cooldown Reduction.
Please refer to the following two videos:
In this first one, my Cluster Seeker has a 20.5 seconds Cooldown with Normal Overclock. When I deploy and cancel the skill, if you time it with a stopwatch, this is actually an effective duration of around 17s because Overlock is active. The 4 seconds reduction corresponds to a 20% reduction.
In this second video, my Cluster Seeker has again a 20.5 seconds Cooldown but this time with Perfect Overclock. Once again timed on a stopwatch it's about 17s for 20% CD reduction.
You can test this with pretty much any skills and it will always come up with the same result.
Conclusion: Overclock and Perfect Overclock are numerically the same.
