I've said it before, and I'll say it again:

You can draw up a scenario where anything is better than anything else, if you get to assume that one of the players will be stupid.

Frankly, if I'm playing a fire warrior and you're playing a storm warrior, you have no chance of catching me without my cold vuln covered in some way (probably a resist cold armor) unless I am absolutely certain it won't swing the fight. None. Bring on the frostbrand and deal me damage I'm resistant to all day.

Is this equally possible for all vulns and characters? No. Is it possible for fire giants and cold? Sure is.
