Your strategy and magic access also relates to what temperature you want. Like if you plan to use undead and encumbrance tactics you probably want extreme temperatures. Does your mage have water or fire magic? If so they can cast cold or fire resistance to deal with the scales.

Take LA Agartha for example. You have no national preference or resistances. But you'll be using undead summons, skelespam, rigor mortis and have fire magic on all mages. Plus I tend to take a light earth bless and plan for Lamia queens. So heat 3 fits nicely there.
