I'll do the opinion since I don't wanna flood gd1.
Flame bolt better in almost all situations.
Either secondary works (I mildly prefer spear* but sway between them over time).
Snapfreeze is very good and has no alts.
I personally prefer flamethrower, but only so much. I can use either effectively. You just have to be aware of what you're running and how that effects how you should play and build.
