Yeah. I just tried it on my 70 mage.
Crate of Kidnapped Pupples was my go-to when I actually did this, but, as the Wowhead comments say, it doesn’t work now. I got 2 hits, but mostly misses.
BTW, where was my mind earlier? Elemental Force is just for adding the freeze, which you can easily do yourself as a mage. D’oh.
Anyway, apart from the freeze, the Wowhead page says 30 hits in 30 seconds.
41% Haste. GCD 1.06. 1.8 dagger. I started a Blizzard, cast a Comet Storm, auto-attacked, cast Ice Lances inbetween, right-clicked as fast as I could. I tried everything I could think of.
No success.
I don’t say it can’t be done, but I am dubious.
