The Legendary Golden Helmet was Silently Nerfed

I don't know when this nerf happened (I noticed it while playing and I'm pretty hardcore to notice my cooldown is incorrect). 

The Golden Helmet went from 25% to 20% in recharge tactical and ultimate cooldown.

I'll use a few example of before and after with Tactical:

Wraith and Pathfinder both had 35 second cooldowns. Before it was 26 seconds (35 * 0.75 = 26.25) Now it is 28 seconds (35 * 0.80 = 28)

Legends with 25 second cooldowns such as Caustic and Bloodhound used to have 19 second cooldowns (25 * 0.75 = 18.75). Now it is a flat 20 seconds (25 * 0.80 = 20)

Wattson fences used to be 23 seconds (30 * 0.75 = 22.5) now they are 24 seconds (30 * 0.80 = 24)

Lifeline used to be 45 seconds (60 * 0.75 = 45) Now it is 48 (60 * 0.80 = 48)

This also affected Legends ultimate charges but I am not going to do the math for that. You can still figure that out by times it by 0.80 vs 0.75.

Wattson/Crypto/Gibby for example used to take 135 seconds from 180 to get an ult with Golden Helmet. It is now 144 seconds from 180. 

Also Crypto Drone becomes 32 seconds if it's destroyed and he has the Golden Helmet. Before it used to be 30 seconds.

Thoughts? I mean, I can understand why Golden Helmet got a nerf if the developers didn't want certain Legends to become too strong with it. I'm not going to list the best legends with it, but Mirage no longer even needs a Golden Helmet how fast his cooldowns are. Octane is the worst until he gets a rework where he actually benefits from the Golden Helmet.
