I literally die in a 4 second stun.Someone stunned you for 4 seconds, and in that 4 seconds (which is what "literally" means), they took 355,000 health off you? So they did nearly 90k DPS with no warm up.
I call shenanigans.
Frost Bomb and Frozen Orb will do more than half of that and that's only one GCD prior to the Deep Freeze, at least pre patch. Now the mage just has to count to two before DF'ing or use Fire Blast. The 65k+ FFB and 50k Ice Lances to follow usually do the rest. I've died with Frozen Orb pulsing ~24k a tick Frost Bomb at ~165k 65k FFB 55k Ice Lances.
That was ~280k damage I took in 2 GCD's during a Deep Freeze without the mage using CD's / Berserking. The damage potential is there, you can't say it isn't.
