Ability not ready for use even after cooldown timer reaches 0

[MyauNei]

I've been out of sync between the cooldown timer's "0" and the actual time a button press will succeed by nearly 10 seconds - I think it's most extreme using a DoL gathering-node-search ability. It seems to me that a little server-client crosstalk could add a latency correction factor (averaging things out, of course).

I have experienced this issue a few times as well. The timers displayed can be greatly off sync when trying to use a long cooldown timer skill such as Exaltation or Tranquility by up to a minute from what I've experienced.
