Yeah. So there is the GCD, and then every spell has its own recast timer. So when you cast Mesmerize, for instance, you'll notice that once the GCD is over the button may still be grayed out for a period of time. Spells in the first slot are castable during this time if you use any clicky. There's a caveat, though. The spell still can't finish casting until after it's individual cooldown has passed. So, as long as the casting time of the spell itself is longer than the spell's cooldown, you can use a clicky to immediately start casting the spell in your first slot after you've casted it.
