Winter Wolf Form

Does winter wolf form make any difference in Kur/GK? It worked well back when they just dealt damage but it doesnt seem to do anything now. From the description (Become a wolf with a thick winter coat of fur) it sounds like it should at least increase max heat or reduce heat decay.

Please correct me if I am wrong but this seems like a small bonus that used to apply to Lycans but no longer applies. Seems pointless to use the form now (other than for aesthetic reasons)

Winter Wolf form grands 5 indirect cold damage mitigation, which reduces decay rate of body heat. Since its so small amount, difference is barley noticable, but it's there.
