Was trying firemage on beta, reading the icy veins fire guide, specifically the "Pyroblast Fishing" portion, and i'm not quite sure I get it.
So for instance, say I fireball, it gets a crit, I then fireblast during my second fireball cast, now I have Hotstreak active, and my second fireball about to land. As I understand it, i'm supposed to let that second fireball cast finish, and immediately use my hotstreak, so they land at a similar time. The idea being that if they both crit, I immediately get another hotstreak, and continue on as I just did.
I've noticed that sometimes fireball will hit first and crit, giving me heating up, then the pyro will hit and not crit, losing me the heating up.
I guess my question is, is there a specific reason not to just immediately use a hotstreak? what exactly does delaying it for another fireball cast do in the long run, does it all not just even out over time?
