Battleskill timing

Some heroes has some wrong/hidden information about battle skill
Example: Nathaniel, with improved battle skill he has 10s cooldown, but for reason of cast animation it real cooldown go to about 12s. Is it should be that way?

0 skill haste & no artifact
no ultimate skill
therefore he must use battle skill at 2 timings sustainly, and that timing mustn't move.
as it wrote, it must cast at that timings(screenshot_1) (correspondly to boss skills 1 & 3), but casts are made at first time here(screenshot_2)(at middle of boss skills between 1&2, 3&4) And after ~20 stacks of damage buff, it casts after another skill(screenshot_3) (after boss skills 2&4).

Also if i cancel at least 1 time battle skill with ultimate, and after will cast ulatimate every 20s. It will every cycle get different casts

Sorry i can't upload 3-4 min edited recordings with visualising to show what i mean correctly

@full mountain
Dear Traveler, Thank you for your patience, we really appreciate.
We would like to let you know that there is a discrepancy between the cooldown displayed on the client and the actual calculation during combat. The client calculates the skill haste first and then deducts the might points for skill upgrade, while the server first deducts the might points and then calculates the skill haste.
We hope the above explanation helps you.
If there're any concerns, it would be highly appreciated if you provide us with a test video from the player for further verification.
Thank you for your support and understanding.
