So my question is mostly, is this roughly how I'm supposed to do it in the scenario where you can't load 5 ammo ahead of time or am I doing something horrendously wrong here?

Last thing I would ask is cooldown related. I've seen it asked and answered earlier so again I'll just ask if this is still the case, because the answer was a long, long time ago. Delaying your 2nd Wild Fire long enough to activate all of B4B, HE, and HC are all ready again is a overall gain instead of just going after B4B and HE are back up. Is that accurate still?

That's all I got. Thanks.
