How to make the most out of T17 4PC

So the tier bonus is fucking gnarly and I love it, but I find a lot of the time I'm either mid cast or in a GCD when the buff comes up. The way I've been handling it is just cancelling whatever I'm doing and spamming pyro's but I feel like I'm losing out on a free pyro by being occupied when I get the buff.

Is there any way to mitigate time lost in the pyro buff? How do you guys handle this?

You should probably finish your current cast, interrupting is always a worse dps loss.

After that spam pyro's like theres no tomorrow

*poof*

While that normally is a good rule to follow, if you are able to react quickly enough that there is more time left on the current cast than your current GCD, I can't see continuing with the cast being a gain under any circumstance.

Even if you can't react quickly enough you're likely giving up a guaranteed Pyroblast crit to finish a Fireball - the direct damage difference alone between those two is pretty massive, even without the Pyroblast! buff.
