No you should really read what i reply to! PLEASE go back and read my first post in this thread including the quote in the very same thread.
yes i always get 2 pyro's in a row for my combustion, NO i dont wait 90s for it. reset time for gaining HS+HU is rarely more than 10s. Now AT ensures me the 3rd 50% of the time. again this is not luck.
Anyway i will leave it here it seems i need 100% crit for you guys to be happy about "not lucky".
you clearly do not want to improve your play, witch i am sure(hope) your raid does not approve of, and neither should you.
Edit:
This is not correct at all. your !pyro is getting used straight after fireball, as the cast time of fireball goes past GCD and you use instant !pyro. so they are both in air when fireball hit. you only have HU when they hit. if ANY of them hit you gain !pyro, if you both crit you regain HS+HU.
further more the most realistic chance of getting HS+HU is not 2xFb crits followed by IB. it is 1xFb crit->Ib->Spam Fb till HS+HU, do one more Fb->!Pyro.
