its really possible too make Pyro during combust and getting more pB with fb proc is easy now.
the rotation will be something like that.
2 sec on pull timer
-pot
-rune of power
-fireball
-combustion
-fB
-pyro
then u have too cycle it untill the end of combustion then u have 4 fb too keep the dps up
its work for me ! im doing all the time 350k+ burst in pre patch will TW
using rune of power is really important
we should call fire mages The new old Arcane's (without mana problem) and it needs more skills too play
