So I'm still stuck on what I really want to craft this into, I have a Heavy Plate Mail with Fire High but I can't tell if I should upgrade it to Volcanic for immunity to Medium Fire or to upgrade it into an Ironmight Plate for resistance against Fire.

I know these armors aren't really used aside from cosmetics nor do I see myself using them much in PvE unless I'm heating but I seriously don't know which one to transform it into. Any suggestions?
