So I'm tired of both NM camping and Caravan and decided to check out Supply Missions. I see that I can trade in steel ingots for seals, cool I thought. Then I saw that I got 6 flame seals per ingot. If I trade in 10 of them I would be a proud owner of 60 flame seals. At this rate it would be much, much quicker to just do either NM camping or Caravan.

Is there something I'm missing here? Are there better options for seals vs materials for DoHs?
