Teleport Haste for 4 seconds not refreshing when Teleport cooldown is on 3,9 or 3,8 seconds cooldown

[Valnayar]

When using the teleport skill with the 4/4 Comet Rush, you get a 4 seconds haste refreshed buff, this works when teleport has a lower cooldown than 4 seconds to keep it refreshed.

However, when the cooldown of teleport is only 3,9 or 3,8 it has a 90% chance of not refreshing. But a 10% of refreshing anyway. This is highly inconsistent and is probably due to the buff being (re-)applies AFTER teleport finishes. Depending on the distance this can maybe influance the 0,1 or 0,2 time gap it has where it should apply the buff again.

Hoping this can be fixed or changed to better reflect the tooltip and expected value of the skill node.

Thank you in advance.

After further testing it always re-applies the buff the first time, but never the second time.

Having Haste > Teleport comet rush: 4secs > recast at 3,8 seconds = refreshed 4 seconds > recast at 3,8 seconds = not refreshed.

This is regardless of the distance traveled. Hope this helps in troubleshooting
