Really wish people stop spreading misinformation like this. It's not even that hard to solo as Frost, as there's so little physical damage. If anything, Kael has gotten easier to solo for all classes with the new talents and glyphs..
But that's not to say that stuff doesn't bug out. On my DK during the Grand Astromancer fight, I had one of her priest adds hit me for 320k holy damage.
