Two observations:
1. You are using an E3D clone, not a genuine one, so you can't expect it to perform as well.
2. Your experiment with the soldering iron suggests to me that you are unaware that you need to keep the top end of the heat break cool, by having a fan blowing cool air over the heatsink. Of course filament will come out of the top if you don't keep it cool.
I doubt that your problem has anything to do with humidity or altitude.

I'm sure the e3d with PTFE liner all the way through it will work fine. But later, I want to print ABS and Nylon, so that is a no go for me. But I think I will order a j-head and e3d clone, without the all-metal, and try those out too. The real e3d is too pricey for me right now, and I am enjoying diagnosing this issue.

In otherwords, the issue really isn't with the e3d or its clones; I see it as really being a Bowden issue - that increased pressure of the filament inside the PTFE, that you have to release with excessive retraction. I think if we eliminate this problem, then all of the e3d printhead issues (when using a Bowden) will largely disappear.

The guidance from E3D for their genuine V6 hot-end is that retraction should never be more than 4mm, as any more would bring the molten tip of the filament up into the cooler part of the heat-break. They recommend that it should normally be a lot less, dependant on the material being used.
More trouble-shooting information here.
Of course, this is for the genuine item, and may not be appropriate for the clones.

There had been a few ideas about "remote stepper extruding" Before you invest time and money, see what others have done ( and what has found the way into the market )
My own idea failed badly from too much friction on the gear. A reduction gear and proper linear bearings would have added too much complicity and weight, too.
