It's disgustingly strong.
The Frost ones at least are weak looking. Fragments is pure AoE by wording, Slick Ice is garbage because it drops Frostbolt sub-GCD in 6 stacks, and the other two are functionally more Orb with different methods of getting there. Compared to a 66% uptime crit damage buff that costs one GCD, they're nothing.
