My ice shard/blizzard/frost nova sorc is doing better than ever thanks in no small part to multiplier passives and enough skill points to now cap shards and frost nova. If I could actually get the ancestral aspect levels for frostblitz I would be casting it non stop. The tweaks to paragon also helped immensely.
I still think the class could use a buff to single target damage but to say that the “mage” has had “total destruction” is very narrow minded at best and complete nonsense at worst.
