Unnatural Resilience and Heatproofing are redundant

Unnatural Resilience and Heatproofing are very nearby on the skilltree and it does not make much sense to ever take Heatproofing as a result. Unnatural Resilience provides some cold/lightning max res, and a huge amount of max fire (trivializing fire damage entirely). Armour builds need something to pair with this node to help deal with cold/lightning, so maybe rework Heatproofing to Weatherproofing, allowing armour to apply to cold/lightning instead at 20%.
