Description: The death knight's grace period does not work correctly. In the video above, you can see that it starts at about 7.8-8 seconds. In fact, the grace period should remain 2.5 seconds. That is, runes in the grace period should have a CD of 7.5 seconds.

How to reproduce: Repeat the steps I performed in the video (Spend all runes for the first time. Wait until they all recover and then at least another 2.5 seconds. And start spending it again).

How it should work: 7.5 seconds CD instead of 7.8-8 (how does it work now)
