So my alt mage just got the legendary metagem, and I'm running into an issue; whenever I'm affected by timewarp and metagem (and sometimes only one of those), the cast time of my fireball is less than the traveltime to the boss, so I can't turn heating up procs into Pyroblast procs with Infernoblast because it doesnt register in time.
What do I do in this situation? Just use pyroblast when it procs and ignore inferno blasting?
