Typical. Don't have an argument, so go about attacking the man. You're simply trying to poison the well by insinuating that I'm not a reliable source because you think I'm getting annoyed. In fact, I am indeed restating my original position, because you never adressed the points. You simply dismissed them and moved the goalposts.
Anyway, unlike you, I'm willing to actual argue based on the argument, not by attacking the person making it. So let's do that.
Point by point
Arc HeatingMy argument : Arc heating is not that harmful, only occurring on the outside of armor. Following graphic evidence provided.

I'd also like to point out that metal does have great conductivity. If it gets heated, it's extremely effective at transferring that heat to whatever it's touching. Which would be you. Really, if the heat's enough to scorch the metal like that, I don't want to be wearing it.
as if it's hot enough to blister paint, it's enough to blister people
Additional note : I may not have made it clear enough, but the Arc happens on the outside of the armor. This means you get a very sharp and very short heat gradient. It does not last long enough to heat up the metal, merely scorches the surface. And anyway, having the spark directly on the skin will always be worse than having armor between.
Electrical resistance heatingMy argument : Metal conducts, therefore there would be insufficient resistance to noticeably heat the material.
Your argument : [I don't think you've mentioned this point much. Others have, so I'll leave this here]
Further notes : This is evidenced by the fact that much thinner lightning rods exist and don't have to be replaced after every strike. A 12 mm copper wire can conduct a lightning strike without issues, and so you can't argue that a lightning strike would heat a far thicker armor to uncomfortable levels.
Lighting messing with your bodyMy argument : Metal conducts far better than skin, no noticeable amount of electricity will pass through.
Your argument: Wet skin conducts better
Note : You're going to have to do better than that. Currently you're posing your opinion as fact despite plenty of evidence (faraday cages, faraday suits, physics, ...) to the contrary.
For the rest, what you've done is move the goalpost. Originally, the point was whether or not lightning should heavily impact armored forces. So, it was a discussion between lightning impacts armor heavier, or lightning impacts armor weakly.
Then, you tried to change the goalposts, pretending that the argument was between whether it should lightly impact armored forces or not impact them at all. This is very dishonest, because from the beginning there was no one who argued against the fact that lightning would have at least some effect.
On a completely unrelated note. The idea that metal attracts lightning is a myth. Lightning is attracted to a point where a charge can build up. That means that the object needs to be high, needs to be pointy, and needs be relatively isolated. So, unless our armor features a 12 meter Pickelhaube, it won't attract lightning at all.
