Since patch I didn't have much time to do any math about this (not even to get deep into 4.0.1 changes lol), but I was wondering wheter spamming scorches to get HS wouldn't yeld more dps than with using fireball ? With faster scorches you could get pyros more often, more often there would be also pyro dot on target therefore more good time windows to use combustion etc etc etc. With talented scorch and mana-free pyros you'd lose mana only for lb and every spell could be cast while moving. Going to test it tomorrow, now it's beer time ;p - thoughts ?
Edit: Rought dummy tests shows difference like 500 dps in favor of using fireball after all (perhaps because of fb being glyphed ?) Dunno what about if I had stacked more crit (and were sober).
