Have someone noticed problems with off-GCD skills.
Example:
/action "Swiftcast" <me>
/action "Medica" <me>
acts really strange:
* Is starts to cast Medica(i see casting bar)
* In 0.5-1 sec it interrupts Medica and casts Swiftcast
* Then i need to press button again for it to cast Medica under effect of Swiftcast

What can it be? Delays/lags?
