Lockdown spell for custom time

[Shokarta]

Hello guys,

basicaly Im looking for addon to lock a spell for a time (2sec) after i click the spell, so it wont be clicable until this custom countdown is finished.

Is anything like this exists already? Or I suppose this would be pretty simple to write, when its basicaly for one spell only, so it can be hardcoded without any "settings" needed

What in reality im looking for is once I click on "Explosive Shot" as surv hunter, it wont let me click again until dot ticks down so I wont miss any tick, basicaly its 2seconds since I clicked on the spell.

Thanks
