Yes i know Lore of Life has some water spells and the Ice Witches of Kislev (they were laylines and ancient human magic though), but seriously why is there no wind of water/ice was it because colors, cause they are lacking orange and indigo on the magic college color wheel. Philosophically and religiously there shouldn't be a problem, the school relates to Manaan and philosophically it could follow a taoist principle of life is like a river where rocks ( events and actions) shapes ones path and knowing when to divert and when to go with the flow.

What i meant to say why is lore of Water/Ice not part of the winds of magic

I think it's because Ice Magic is more akin to divine magic, like what priests of Sigmar can do, at least for Kislev.
